 11 Claims, No Drawings HYDROFORMYLATION USING AGED ZEOLlTE-ALUMINA HYDROSOL DISPERSION oxide and hydrogen at the original position of the unsaturated bond with a minimum amount of isomerization prior to the hydroformylation by effecting said hydroformylation in the presence of a zeolite which has been dispersed in an alumina hydrosol prior to aging at elevated temperatures.  
  Processes directed to the production of reaction mixtures comprising substantial amounts of aldehydes and alcohols by the hydroformylation of unsaturated compounds with carbon monoxide and the hydrogen in the presence of certain catalysts are well-known in the art. The aldehydes and alcohols produced generally correspond to the compounds obtained by the addition of a carbonyl or carbinol group to an olefinically unsaturated carbon atom in the starting material with simultaneous saturation of the olefin bond. The process is known as hydroformylation and it involves a reaction wihch may be shown by the general generic formula:  
 (1) R R R H l I l R1-G= c-R +co+ii 3.  
 l l l where R,. R R R, may be chosen from a group comprising an organic. halide or hydrogen radical.  
  It has been shown in the prior art that dicobalt octacarbonyl has generally been used as the catalyst for the hydroformylation of the unsaturated compounds. This catalyst. which can be prepared from many forms of cobalt. usually decomposes rapidly unless high pressures of about 2004.500 lbs. per sq. inch gauge of carbon monoxide are maintained. Correspondingly high pressures of hydrogen are also necessary. Another disadvantage inherent in the hydroformylation is a relative inability to direct the reactions involved to the production of products arising from the hydroformylation at the original position of the unsaturated compounds when predominantly terminal unsaturated compounds are utilized.  
  ln contradistinction to the prior art. it has now been shown that the presence of a zeolite which has been dispersed in an alumina hydrosol prior to aging at an elevated temperature will effect the hydroformylation to occur at the original site of the olefinic bond. The utilization ofthe present invention will enable the manufacturer to more accurately determine the resultant position ofthe alcoholic or aldehydic moiety. as the olefinic bond has less tendency to isomerize during hydroformylation. The manufacturer will also be allowed to produce branched chain alcohols and aldehydes which can be used as intermediates in the preparation of detergents and wetting agents. said compounds possessing excellent wetting ability and foam stability. but lower fish toxicity as a result of the utilization of the present invention. Yet another advantage which occurs as a result of the utilization of the set forth invention is that the presence of the treated zeolite does not create an increase in an undesirable products such as alkanes.  
  The desired products of the process of this invention. namely alcohols and aldehycles. are utilized in the chemical industry in many ways. For example. alcohols are utilized in the synthesizing of other organic derivatives. as solvents. as an extraction medium. in dyes. synthetic drugs. synthetic rubbers. detergents. cleaning solutions. surface coatings. cosmetics. pharmaceuticals. in the preparation of esters. as a solvent for resin in coatings. in plasticizers. dyeing assistants. hydraulic fluids. detergent formulations and dehydrating agents. Aldehydes are utilized as perfumeries or precursors to perfumeries. or in the synthesis of primary alcohols. The non-linear alcohols and aldehydes are also utilized in the chemical industry in many other ways; for example. Z-methyl-l-butanol is utilized as a solvent in varnishes. lacquers and paint removers. Likewise. a general use of the non-linear alcohols and aldehydes is in detergent formulations as exemplified by Z-hexyl-lheptanol.  
 &#39; It is therefore an object of this invention to provide a process for the preparation of alcohols and aldehydes.  
  A further object of this invention is to provide an improvement in a process for the preparation of alcohols and aldehydes utilizing a zeolite in order to produce a greater percent of alcohols and aldehydes in a more expedient manner. said zeolite having been dispersed in an alumina hydrosol prior to aging at elevated tempera- R2 R3 OH l l l H R4 H tures.  
  In one aspect an embodiment of this invention rcsides in a process for the preparation of an alcohol or an aldehyde which comprises hydroformylating an unsaturated compound possessing four or more carbon atoms by treatment with hydrogen and carbon monoxide at reaction conditions in the presence of a catalyst comprising a cobalt-containing compound and recovering the resultant alcohol or aldehyde compound. the  
 improvement which consists in reducing the amount of isomerization prior to hydroformylation by effecting said hydroformylation in the presence of a zeolite which has been dispersed in an alumina hydrosol prior to aging at elevated temperatures in the range of about 30C to about 500C.  
  A specific embodiment of this invention resides in a process for the hydroformylation of decene-S which comprises the treatment of decene-S with carbon monoxide and hydrogen in the presence of a catalyst comprising dicobalt octacarbonyl at a temperature in the range of from about C to about 200C and a pressure of atmospheres of hydrogen and 120 atmospheres of carbon monoxide. said hydroformylation also being effected in the presence ofa zeolite comprising l5 /r mordenite which has been dispersed in a 67% aluminum chloride-33% aluminum sulfate sol prior to aging at a temperature in the range of from about 100C to about C and a pressure in the range of from about 1 atmosphere to about 100 atmospheres for a period of time comprising five hours. thereby producing Z-pentyLl-hexanol.  
  Another specific embodiment of this invention resides in a process for the hydroformylation of tetradecene-7 which comprises the treatment of the tetradecene-7 with carbon monoxide and hydrogen in the presence of a catalyst comprising dicobalt octacarbonyl at a temperature at llC and a pressure of I20 atmospheres of hydrogen and 120 atmospheres of carbon monoxide. said hydroformylation also being effected in the presence of a zeolite comprising l0&#39; mordenite dispersed in an aluminum chloride hydrosol prior to aging at a temperature of 400C and a pressure of l atmosphere for a period of time comprising ten hours. thereby producing Z-heptyl-l-octanol.  
  Another specific embodiment of this invention resides in a process for the hydroformylation of hexadecene-l which comprises the treatment of hexadecene-l with carbon monoxide and hydrogen in the presence of a catalyst comprising dicobalt octacarbonyl at a temperature of l 10C and a pressure of 120 atmospheres of carbon monoxide and I atmospheres of hydrogen. said hydroformylation also being effected in the presence of a zeolite comprising l571 mordenite which has been dispersed in a 67% aluminum chloride-33% aluminum sulfate sol prior to aging at a temperature in the range of 100C to about 150C and a pressure in the range of about 1 atmosphere to about 100 atmospheres for a period of time comprising 5 hours. thereby producing heptadecanol-l.  
  Other objects and embodiments will be found in the following further detailed description of the present invention.  
  As hereinbefore set forth the present invention is concerned with a process for preparing alcohols and aldehydes. said process being effected by the hydroformylation of an unsaturated compound with carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt-containing compound. The hy droformylation is effected under conditions which include a temperature of from about 75C to about 300C and preferably in a range of about 100C to about 200C. ln addition. another reaction condition involves pressure. said pressure ranging from atmospheric up to 500 atmospheres or more. When superatmospheric pressure is employed. said pressure is afforded by the introduction of gaseous carbon monoxide or hydrogen to the reaction zone or. if so desired. the pressure may be partially afforded by the carbon monoxide or hydrogen while the remaining pressure is afforded by a substantially inert gas such as nitrogen. helium or carbon dioxide. although not necessarily with equivalent results.

  The catalytic compositions of matter which are used in the process of this invention comprise compounds containing cobalt such as dicobalt octacarbonyl.  
  It is also contemplated within the scope of the process of the present invention that the hydroformylation may be effected in an inert organic media as exemplified by n-pentane. n-hexane. n-heptane. n-octane. nnonane. isooctane (2.2.4-trimethylpentane). cyclohexane. methylcyclohexane, benzene. toluene. m-xylene. mesitylene. etc. It is understood that the aforementioned inert organic media are only representative of the class of compounds which may be employed. and that the present invention is not necessarily limited thereto.  
  The process of the present invention. as hereinafter set forth in greater detail. demonstrates that the presence of a zeolite will reduce the isomerization of the olefin which occurs prior to hydroformylation. said zeolite having been dispersed in an alumina hydrosol prior to aging at elevated temperatures. Zeolites as hereinbefore set forth are contemplated to include all aluminosilicates. both natural and synthetic. including mordenite and faujasite.  
  Zeolites are crystalline aluminosilicates comprising cages or cavities interconnected by smaller pores or channels of definite size range characteristic of each zeolitic variety. Since the dimensions of the pores and channels are such as to accept molecules of certain dimension while rejecting those of larger dimensions the materials have come to be known as molecular sieves and are utilized in many ways taking advantage of these properties.  
  The zeolites are generally described as a threedimensional network of fundamental structural units consisting of silicon-centered SiO and aluminumcentered AIO tetrahedra interconnected by a mutual sharing of apical oxygen atoms to effect a chemical balance. each AlO tetrahedra has a cation associated therewith. typically sodium. The SiO and M0 tetrahedra are arranged in a definite geometric pattern often visualized either in terms of chains. layers or polyhedra. The zeolites comprise well-defined intracrystalline dimensions including intra-crystalline channels and pores whose narrowest cross-section has essentially a uniform diameter. The various zeolites may be classified according to the geometric pattern of their framework with its attendant pore size. and by the SiO- :Al O mole ratio of their compositions.  
  One type of zeolitic catalyst contemplated within the scope of this invention is mordenite. Mordenite is highly siliceous in nature and characterized by a SiO :Al. ,O;, mole ratio of from about 6 to about 12 as manufactured or found in its natural state. The mordenite crystal structure comprises four and five membered methoxybutene-Z.  
 rings of SiO- and AIO. tetrahedra so arranged that the resulting crystal lattice comprises pores and channels running parallel along the crystal axis to ive a tubular configuration. Mordenite is unique among zeolites since the channels or tubes do not intersect and access to the cages or cavities is in only one direction. thereby giving the zeolitic structure its two-dimension configuration.  
  Another type of zeolitic catalyst contemplated within the scope of this invention is faujasite. Faujasite is characterized by a SiO- aAl. O;; ratio of about 2 to about 6 and by pore openings in the range of from about 6 to about Angstroms. The fundamental structural units. SiO., and M0 tetrahedra. are joined to form fourmembered and six-membered rings and the rings are so arranged that the resulting structure resembles a truncated octahedron with the four-membered ring forming six sides or faces thereof and the six-membered ring forming the remaining eight sides or faces. The resulting truncated octahedra are interconnected at the hexagonal faces through a hexagonal prism formed by two of the six-membered rings of tetrahedra to form a crystal lattice comprising cavities or cages in open communication through channels. thereby giving the zeolitic structure is three-dimensional configuration. Other natural zeolites which may be utilized include analcite. chabazite. heulandite. natrolite. stilbite and thomsonite. It is also contemplated within the scope of the process of this invention that synthetic zeolitic catalyst may also be utilized. The synthetic zeolites would include all those varities ranging from gelatinous to porous or sandlike.  
  The above mentioned zeolite is treated by a dispersion in an alumina hydrosol prior to aging at elevated temperatures. The treatment is a two-step process: first where the zeolite is dispersed within an alumina hydrosol. and second when it is aged at elevated temperature in the range ofabout 45C to about 200C and preferably in the range of about 90C to about 160C fora period of time from I to hours or more. An alumina hydrosol may be prepared from compounds such as aluminum chloride. aluminum bromide. aluminum sulfate. aluminum alcoholate. etc.. the aluminum chloride being the most generally employed. Suitable examples of alumina hydrosols would include aluminum halide hydrosols. such as aluminum chloride sols, aluminum bromide sols. aluminum-chlorosulfate hydrosol and aluminum acetate hydrosol.  
 The process of this invention may be effected in any suitable manner and may comprise either a batch or continuous type operation. For example. when a batch type operation is employed. the reactant comprising the unsaturated compound. is placed in an appropriate apparatus along with a catalyst comprising a cobaltcontaining compound plus the presence of a mordenite-alumina or faujasite-alumina (which had previously been heated to an elevated temperature for a predetermined increment of time to effect aging). The autoclave is sealed. carbon monoxide and hydrogen are pressed in until the desired operating pressure is reached. heated to a desired operating temperature and maintained thereat fora predetermined period of time. At the end of this time. which may comprise from about 0.5 to about 20 hours or more in duration. the heating is terminated and the autoclave vented. thereby allowing the autoclave to return to room temperature and ambient pressure. The reaction mixture is then recovered. separated from the catalyst and the mordenite-alumina or faujasite-alumina. and subjected to conventional means of purification and separation. said means including washing. drying. extraction. evaporation. fractional distillation. etc.. whereby the desired alcohol or aldehyde is recovered.  
  It is also contemplated within the scope of this invention that the reaction process for obtaining the desired alcohols and aldehydes may be effected in a continuous manner of operation. When such a type of operation is employed. the catalyst and the reactants. namely a cobalt-containing compound dissolved in an unsaturated compound. the carbon monoxide and the hydrogen. are continuously charged to the reaction vessel containing a mordenite-alumina or faujasite-alumina (which had previously been heated to an elevated temperature for a predetermined increment of time to effect aging). The hydroformylation vessel is maintained at predetermined operating conditions of both temperature and pressure effected by the ingress of additional carbon monoxide and hydrogen. After completion of the desired residence time. the reactor effluent is continuously withdrawn and subjected to conventional means of separation whereby the desired alcohols and aldehydes are separated from the cobalt and recovered. while any unreacted starting materials comprising the unsaturated compound. carbon monoxide. or hydrogen are recycled to the reaction zone to form a portion of the feedstock. Inasmuch as the zeolite is solid in nature. various types of continuous operation may be used. One such type of operation comprises the fixed bed method in which the zeolite is disposed as a fixed bed in the reaction zone and the reactants and catalyst comprising the unsaturated compound. carbon monoxide. hydrogen and the cobalt catalyst are passed over the said fixed bed in either an upward or downward flow. Another type of operation which may be employed comprises the moving bed type operation in which the zeolite and the reactants plus catalyst are passed concurrently or countereurrently to each other. or the slurry type operation in which the zeolite is carried into the reaction zone as a slurry in the unsaturated compound. The cobalt values may be recovered from the reaction mixture by various methods known to the art and regenerated to form fresh catalyst.  
  Examples of alcohols and aldehydes which may be prepared according to the process of this invention would include the terminal alcohols and aldehydes when an alpha olefin or an alpha unsaturated compound is utilized as the starting material plus hydroformylation products which are non-linear in structure. Suitable examples of terminal alcohols and aldehydes would include 2-methyl-l-pentanol. 3-ethyl-l-hexanol. Z-propyll-heptanol. 3-ethyll -octanol. Z-ethyl- 1 nonanol. 3-amyl-l-nonanol. 4-amyl-l-decanol. 3- hexyll -decanol. 3-heptyll-deeanol. 4-propyl l undecanol. 3-amyll undecanol. S-heptyl-l-dodecanol. 3-propyl-l-undecanol. o-heptyl-l-tridecanol. 3-propyll-tetradecanol. S-octyI-I-pentadecanol. S-nonyl-lheptadecanol. 2-pentyl-l-hexanol. Z-heptyl-l-octanol. Z-hexyll -heptanol. 2hexyll-octanol. Z-heptyll octanol. Z-hexyl-l-heptanal. Z-hexyl-l-octanal. Z-heptyl-l-octanal. S-heptyl-ltetradecanal. 3-propyl-lheptadecanal. l-pentanol. l-hexanol. l -heptanol. loctanol. l-nonanol. l-decanol. l-undecanol. ldodecanol. l-tridecanol. l-pentadecanol. heptadecanol. etc.  
  The following examples are given to illustrate the process of the present invention which. however. are not intended to limit the generally broad scope of the present invention in strict accordance therewith.  
 EXAMPLE 1 In this example. 145.0 millimoles of decene-5 were added to an 850 milliliter glass-lined rotating autoclave containing 1.0millimo1es of dicobalt octacarlmnyl. dissolved in 5 milliliters of n-pentane. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave was sealed. pressurized by the entry of 120 atmospheres of carbon monoxide and 120 atmospheres of hydrogen. heated to a temperature of 1 C and maintained thcreat fora period oftime comprising one hour. At the end of the one hour period of time. the heating was terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen were carefully vented thereby allowing said autoclave to return to ambient pressure. At this point. the product was removed from the glass-lined rotating autoclave and analyzed by means of gas-liquid chromatography instrumentation. said analysis disclosed an percent conversion of the deccnc-S and a 33 percent linear selectivity as defined by the linear products divided by the total products expressed as a percentage. the non-linear products comprising mostly 2-pentyl-l-hexanol. It should also be noted that the analysis disclosed a zero percentage of decane formation.  
 EXAMPLE 11 In this example the experiment of Example 1 was reproduced. maintaining the same physical constants. The gas chromatography analysis of Example 11 product mixture disclosed a percent conversion of decone-5. a 31 percent linear selectivity and a zero percentage of decane formation.  
 EXAMPLE 111 In this example the zeolite-dropping sol blend was prepared by digesting72o grants of a basic aluminum sulfate slurry (6.89 percent alumina) with 769 grams of an aluminum chloride hydrosol (13.0 percent aluminum: 1.24 aluminum to chlorine ratio) in the presence of 60 grants of mordenite for about 4-5 hours at a temperature of C to C. This resulted in 900 cc of an aluminum-chloro-sulfate hydrosol plus mordenite. The sol was cooled and blended with 450 cc of 28 percent HM&#39;T (hexamethylenc tetramine) and 50 grams of urea in an aqueous solution amounting to a total of 100 cc. and formed into 1/16 inch spheroidal hydrogel spheres which were then transferred to a pressure aging vessel and aged 1.5 hours at 150C. The aged spheres were transferred to a wash tower and washed for 3 hours at a temperature of 95C with 5 gallons of water containing 20 grants of ammonium nitrate and 20cc of aqueous ammonia (28 percent). The washed spheres were removed from said wash tower and dried at 149C after which they were -alcined for 2 hours at 649C. the finished catalyst being 15 percent by weight mordenite.  
  Five (5.0) grams of the above prepared treated mordenite catalyst were added to a rotating autoclave to which are subsequently added 145.0 millimoles of decene-S and 1.0 millimole of dicobalt octacarbonyl. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave was sealed. pressurized by the entry of 120 atmospheres of carbon monoxide and 120 atmospheres of hydrogen. heated to a temperature of C and maintained thereat for a period of time comprising 1 hour. At the end of the 1 hour period of time. the heating was terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen were carefully vented thereby allowing said autoclave to return to ambient pressure. At this point. the product was removed from the glass-lined rotating autoclave and analyzed by means of gas-liquid chromatography instrumentation. said analysis disclosed an 85 percent decene-S conversion and a 16 percent linear selectivity. the increase in the non-linear compounds stemming from the increased presence of Z-pentyl-lhexanol. 1t should also be noted that the analysis disclosed a zero percentage of decane formation.  
  It can be seen by a comparison of Examples 1 and 11 with Example 111 that the presence of the treated mordenite-alumimi produced an increase in the percentage of non-linear compounds by an average of 16% (a 50 percent increase). indicating less isomerization of the olefin prior to hydroformylation.  
 EXAMPLE W In this example the zeolite-dropping sol blend comprises 800 grams of aluminum-chloride hydrosol; 75 grams of mordenite were disposed in the aluminumchloride hydrosol for about 5 to 6 hours at a temperature of 105C. This resulted in 950 cc of an aluminumchloride hydrosol plus mordenite. The sol was cooled and blended with 450 cc of 28 percent HMT (hexamethylene tetramine) and 50 grams of urea in an aqueous solution amounting to a total of 100 cc. and formed into 1/16 inch spheroidal hydrogel spheres which were transferred to a pressure aging vessel and aged 1.5 hours at 150C. The aged spheres were transferred to a wash tower and washed for 4 hours at a temperature of 100C with 5 gallons of water containing 20 grams of ammonium nitrate and 20 cc of aqueous ammonia (28 percent). The washed spheres were removed from said wash tower and dried at 177C after which they were calcined for 2 hours at 649C. the finished catalyst comprising 10 percent by weight mordenite.  
  Five (5.0) grams of the above prepared treated mordenitc catalyst were added to a rotating autoclave to which was subsequently added 500 millimoles of hexadecene-l and l millimole ofdicobaltoctacarbonyl.said autoclave being equipped with heat and pressure attainment devices. The rotating autoclave was sealed. pressurized by the entry of atmospheres of carbon monoxide and 120 atmospheres of hydrogen. heated to a temperature of 1 10C. and maintained thereat for a period of time comprising 8 hours. At the end of the 8 hour period of time. the heating was terminated thereby allowing the rotating autoclave to return to room temperature. and the carbon monoxide and hydrogen were carefully vented thereby allowing said autoclave to return to ambient pressure. At this point. the product was removed from the glass-lined rotating autoclave and analyzed by means of gas-liquid chroma tography instrumentation. said analysis disclosed a 75 percent hexadecene-l conversion. and a 70% linear selectivity. the linear selectivity stemming from the in creased hydroformylation of the olefin at its original position. namely l-heptadecanol. The experiment was repeated under the same physical conditions with the exception that the treated zeolite was omitted. The gasliquid chromatographic analysis of this reaction disclosed that the products possessed only a 43% linear selectivity.  
  It can be seen by comparison of these two reaction products that the presence of the treated mordenitealumina created an increase in the percentage of compounds arising from the hydroformylation at the original position of the unsaturated bond. The starting olefin was an alpha olefin. which was reflected in a higher linear selectivity product utilizing the treated morde nite-alumina zeolite.  
 EXAMPLE V In this example. the zeolite-dropping sol blend is prepared by digesting 1710 grams of basic aluminum sulfate slurry with 660 grams of aluminum-chloride hydrosol in the presence of 60 grams of mordenite for about 4 to 5 hours at a temperature of 105C. This results in 950 cc of an aluminum chloro-sulfate hydrosol plus mordenite. The sol is cooled and blended with 450 cc of 28 percent HMT (hexylmethylene tetramine) and 50 grams of urea in an aqueous solution amounting to a total of 100 cc. and formed into l/16 inch spheroidal hydrogel spheres which are then transferred to a pressure aging vessel and aged 1.5 hours at 150C. The aged spheres are transferred to a wash tower and washed for 3 hours at a temperature of95C with 5 gallons of water containing 20 grams of ammonium nitrate and 20 cc of aqueous ammonia (28 percent). The washed spheres are removed from said water tower and dried at 149C after which they are calcined for 2 hours at 649C. the finished catalyst comprising 15 percent by weight mordenite.  
  Five (5.0) grams of the above prepared treated mordenite catalyst are added to a rotating autoclave to which is subsequently added 1450 millimoles of decene-5 and l millimole of dicobalt octacarbonyl. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave was sealed. pressurized by the entry of 120 atmospheres of carbon monoxide and 120 atmospheres of hydrogen. heated to a temperature of l 10C and maintained thereat for a period of time comprising 1 hour. At the end of the 1 hour period of time. the heating is terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen are carefully vented thereby allowing said autoclave to return to ambient pressure. At this point. the product is removed from the glass-lined rotating autoclave and analyzed by means of gas-liquid chromatography instrumentation. said analysis disclosing a high percent decene-S conversion and a low percent linear selectiw ity. the increase in the non-linear compounds stemming from the increased presence of Z-pentyl-l-hexanol.  
  It can be seen by a comparison of Examples 1 and 11 with Example V that the presence of the treated mordenite-alumina created an increase in the percentage of compounds arising from the hydroformylation of the unsaturated bond at its original position.  
 EXAMPLE V1 In this example the zeolite utilized is the same as that prepared in Example V shown. The reaction conditions are maintained at the same level with the exception of a temperature increase in the hydroformylation reaction of from 1 10C to 150C. The product is again analyzed by gas-liquid chromatography instrumentation. said analysis disclosing a percent decene-5 conversion and an 1 1 percent linear selectivity. the increase in the non-linear compound stemming from the increased presence of Z-pentyl-l-hexanol. The analysis also discloses a 1 percent yield of decane.  
  It can be seen by comparison of Examples I and 11 with Example V1 that the presence of the treated mordenite-alumina creates an increase in the percent age of non-linear compounds by an average of 21 percent (a greater than 50 percent increase).  
 EXAMPLE V11 In this example the zeolite utilized is that as prepared in Example V above. The reaction conditions are maintained constant as in Example V above with the exception that the temperature of hydroformylation is raised to 195C. The product is again analyzed by gas-liquid chromatography instrumentation. said analysis disclosing a high percent conversion of decene-5. and a low percent linear selectivity. the increase in the non-linear compounds stemming from the increased presence of Z-pentyl-l-hexanol. The analysis also disclosed a low percentage of decane present.  
  It can be seen by a comparison of Examples 1 and 11 with Example V11 that the presence of the treated mordenite-alumina created an increase in the percentage of compounds arising from the hydroformylation of the olefinic bond at its original position.  
 EXAMPLE Vlll In this example the zeolite is treated as set forth in Example 111 with the exception that faujasite is substituted in place of the mordenite.  
  Nine (9.0) grams of the above mentioned treated faujasite is added to an 850 milliliter glass-lined autoclave to which is subsequently added 145.0 millimoles of a mixture of dodecene-S. tridecene-6 and tetradecene-7 plus 1.0 millimole of dicobalt octacarbonyl. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave is sealed. pressurized by the entry of 120 atmospheres of carbon monoxide and 120 atmospheres of hydrogen, heated to a temperature of C and maintained thereat for a period of time comprising 8 hours. At the end of the 8 hour period of time. the heating is terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen are carefully vented. thereby allowing said autoclave to return to ambient pressure. At this point the product is removed from the glass-lined rotating autoclave and analyzed by means of-gas-liquid chromatography instrumentation. said analysis discloses a higher percentage of non-linear products than would have been expected from a hydroformylation if the treated faujasitealumina had been excluded. namely due to the increase in the percentage of Z-hexyl-l-heptanol. Z-hexyl-loctanol and Z-heptyl- 1 -octanol.  
 EXAMPLE 1X In this example the zeolite which is utilized was that as prepared in the set forth procedure of Example 111. Five (5.0) grams of the above mentioned treated mordenite-alumina is added to an 850 milliliter glasslined rotating autoclave to which is subsequently added 145.0 millimoles of tetradecene-7 and 1 millimole of dicobalt oetacarbonyl. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave is sealed. pressurized by the entry of 80 atmospheres of carbon monoxide and 40 atmospheres of hydrogen. heated to a temperature of 100C and maintained thereat for a period of time comprising l hour. At the end of the 1 hour period of time. the heating is terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen are carefully vented. thereby allowing said autoclave to return to ambient pressure. At this point. the product is removed from the glasslined rotating autoclave and analyzed by means of gaslined chromatography instrumentation. said analysis disclosing a higher percentage of non-linear products than would have been expected from a hydroformylation if the treated mordenite-alumina had been excluded. namely due to the increase in the percentage of Z-heptyl-l-octanol.

  Six (6.0) grams of the above mentioned treated mordenite-alumina is added to an 850 milliliter glasslined rotating autoclave to which is subsequently added 150.0 milliliters of butene-Z and .9 millimoles ol dicobalt octacarbonyl. said autoclave being equipped with heating and pressure attainment devices. The rotating autoclave is sealed. pressurized by the entry of 80 atmospheres of carbon monoxide and 50 atmospheres of hydrogen. heated to a temperature of 150C and maintained thereat for a period of time comprising 90 minutes. At the end of the 90 minute period of time. the heating is terminated thereby allowing the rotating autoclave to return to room temperature and the carbon monoxide and hydrogen are carefully vented. thereby allowing said autoclave to return to ambient pressure. At this point. the product is removed from the glasslined rotating autoclave and analyzed by means of gasliquid chromatography instrumentation. said analysis disclosing a higher percentage of non-linear products than would have been expected from a hydroformylation if the treated mordenite-alumina had been excluded. namely due to the increase in the percentage of Z-ethyll-propanol.
