     When R 1 , R 1  &#39; and R 1  &#34; are residues of fatty alcohols, they are preferably alkyl groups, more preferably n-alkyl groups, having the indicated number of carbon atoms. 
     The compounds of formula I wherein n is 1 and the terminal groups --(OA) x  OR 1  are identical may be produced by a two-step reaction wherein a compound of formula II, 
     
         R.sub.1 --(OC.sub.a H.sub.2a).sub.x OH                     II 
    
     wherein R 1  and x are as defined in formula I and a is an integer 2 to 6, reacted with a phosphorylating agent, preferably phosphoryl chloride, under substantially anhydrous conditions at a temperature of -10° - 100° C., preferably 0°-90° C., more preferably, 20°-70° C. in a molar ratio of 1:1 to produce a compound of formula III, ##STR11## wherein R 1 , a and x are as defined above. Preferably, the reaction mixture is swept by an inert atmosphere to displace the by-product, HCl. 
     As is well known to those skilled in the art, the reaction time necessary is inversely related to the reaction temperature, i.e., the higher the reaction temperature, the shorter the reaction time. It is, therefore, impossible to give a precise reaction time. However, a reaction time of 15 minutes --24 hours is generally acceptable with a reaction time of 30 minutes -20 hours being preferred. 
     Although the reaction is preferably conducted under substantially anhydrous conditions, an inert, organic solvent may be employed as a processing aid. Any inert, organic solvent which is adapted to dissolving the reactants and reaction product and has a boiling point at or above the desired reaction temperature may be used. Suitable solvents are known and available and include, by way of illustration, an aromatic solvent, e.g., benzene or toluene. 
     By the phrase &#34;swept by an inert atmosphere&#34; is meant purging the reaction with nitrogen, helium, neon, argon, krypton or xenon, or a mixture thereof. 
     The second step involves the reaction of a compound of formula III with a compound of formula IV, 
     
         HO--C.sub.a H.sub.2a O).sub.b H                            IV 
    
     wherein a is as defined above and b is an integer 2 to 30, in a molar ratio of 2:1. The reaction is carried out under substantially anhydrous conditions at a temperature of -10°-100° C., preferably 10°-70° C., more preferably 10° C. and is preferably swept by an inert atmosphere to displace the by-product, HCl. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     As in the case of the first step, a precise reaction time cannot be given because the higher the reaction temperature, the shorter the reaction time. However, a reaction time of 15 minutes - 4 days, preferably, 30 minutes--3 days, is generally employed. 
     Any inert, organic solvent in which the reactants are soluble and which has a boiling point at or above the desired reaction temperature may be employed as a processing aid. 
     The compounds of formula I wherein n is 1 and the terminal groups --OA) x  OR 1  are identical may also be produced by a two-step reaction wherein a compound of formula IV, as defined above, is reacted with a phosphorylating agent, preferably, phosphoryl chloride, in a molar ratio of phosphorylating agent to to compound of formula IV of 2:1 under the same reaction conditions described above with respect to the first step, hereinafter referred to as first-step reaction conditions, to obtain a phosphochloridate compound of formula V, ##STR12## 
     The second step involves the reaction of the phosphochloridate compound with a compound of formula II, as defined above, in a molar ratio of 1:2 under the same reaction conditions described above with respect to the second step, hereinafter referred to as second-step reaction conditions. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     The compounds of formula I wherein n is 1 and the terminal groups --OA) x  OR 1  are different may be produced by a stepwise reaction comprising reacting a compound of formula II, as defined above, with a phosphorylating agent, preferably phosphoryl chloride, in a molar ratio of 1:1 to produce a compound of formula III, as defined above under first-step reaction conditions. The second step involves the reaction of a compound of formula III with a compound of formula IV, as defined above, in a molar ratio of 1:1 to produce a compound of formula VI, ##STR13## wherein R 1 , a, b and x are as defined above, under second-step reaction conditions. The third step involves the reaction of a compound of formula VI with an equimolar amount of the phosphorylating agent employed above in the first step to produce a compound of formula VII, ##STR14## wherein R 1 , a, b and x are as defined above. The final step involves the reaction of a compound of formula VII with an equimolar amount of a compound of formula II which is different from that employed in the first step. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     The third step is carried out under first-step reaction conditions, whereas the final step is carried out under second-step reaction conditions. 
     The compounds of formula I wherein n is 1 and the terminal groups --OA) x  OR 1  are different may also be produced by a two-step reaction wherein two different compounds of formula II, as defined above, are reacted with a phosphorylating agent, preferably phosphoryl chloride, in a molar ratio of phosphorylating agent to each of the compounds of formula II of 1:1 to produce two different compounds of formula III, as defined above, under first-step reaction conditions. 
     The second step involves the reaction of the compounds of formula III with a compound of formula IV, as defined above, in a molar ratio of 2:1 under second-step reaction conditions. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     The compounds of formula I wherein n is 2 may be produced by a step-wise reaction wherein the first three steps are identical to that described above regarding the process for preparing compounds of formula I wherein n is 1 and the terminal groups --OA) x  OR 1  are different. The fourth step involves the reaction of a compound of formula VII, as defined above, with an equimolar amount of a compound of formula IV, which may be the same or different from that employed in the second step, to produce a compound of formula VIII, ##STR15## wherein R 1 , a, b and x are as defined above. The fifth step involves the reaction of a compound of formula VIII with an equimolar amount of the phosphorylating agent employed in the first and third steps to produce a compound of formula IX, ##STR16## wherein R 1 , a, b and x are as defined above. The reaction concludes with a final step involving the reaction of a compound of formula IX with an equimolar amount of a compound of formula II, which may be the same or different from that employed in the first step. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     The fourth and final steps are carried out under second-step reaction conditions, whereas the fifth step is carried out under first-step reaction conditions. 
     The compounds of formula I wherein n is 2 may also be produced by a two-step reaction wherein a compound of formula IV, as defined above, is reacted with a phosphorylating agent, preferably phosphoryl chloride, in a molar ratio of phosphorylating agent to a compound of formula IV of 1:2 under first-step reaction conditions to obtain a compound of formula X, ##STR17## wherein a and b are as defined above. 
     Depending upon the ester product desired, the second step either involves the reaction of a compound of formula X, as described above, with a compound of formula III, as described above, in a molar ratio of 1:2, which results in a compound wherein the terminal groups --OA) x  OR 1  are identical, or involves the reaction of one mole of a compound of formula X, as described above, with one mole each of two different compounds of formula III, as described above, which results in a compound wherein the terminal groups --OA) x  OR 1  are different. 
     In either instance, the reaction is carried out under second-step reaction conditions. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     Where compounds of formula I wherein n is 3 are desired, either 2 moles of a compound of formula VII, as defined above, or 1 mole each of two different compounds of formula VII is reacted with 1 mole of a compound of formula IV under second-step reaction conditions. The resultant product is then hydrolyzed and, preferably, neutralized to produce the final ester product in salt form. 
     Although phosphoryl chloride is the preferred phosphorylating agent, the compounds of formula I may also be produced by gradually introducing phosphorus pentoxide to a mixture comprising at least one compound of formula II and a compound of formula IV in a proportion such that the total number of equivalents combiined of at least one compound of formula II and a compound of formula IV to the number of equivalents of phosphorylating agent, calculated as phosphorus pentoxide (P 2  O 5 ), is within the range from about 1.5:1 to 3:1. The reaction is exothermic and the addition of the phosphorus pentoxide should be controlled as to prevent the temperature from rising to the boiling point of the mixture. In general, the reaction is conducted at a temperature range between 40° C. and 160° C., preferably between 50° C. and 100° C. Preferably, the reaction mixture is vigorously stirred during the addition of the phosphorus pentoxide to ensure a uniform and maximum rate of reaction within the controlled range of temperatures. When all of the phosphorus pentoxide has been added, the reaction mixture is held at the reaction temperature for at least an additional 60 minutes to ensure completeness of reaction. After cooling the resultant mixture to room temperature and separating out any unreacted phosphorus pentoxide, a mixture of compounds is obtained, predominant of which is the desired compound of formula I. In this connection, it is believed that the molecules of the compound(s) of formula II and the molecules of the compound of formula IV are linked together in the larger molecule through an intermediate orthophosphate bridge and that less than all of the orthophosphate protons are consumed by the ester bonds, so that chiefly monohydrogen orthophosphate and to a minor degree dihydrogen orthophosphate esters are obtained. 
     The compounds of formula II which are utilized in preparing the compounds of the instant invention represent a widely recognized class of compounds comprising fatty alcohols, mono- or dialkylphenols and the corresponding alkyleneoxy derivatives thereof, preferably, the ethyleneoxy derivatives. The fatty alcohol ethoxylates comprise the condensation product of aliphatic alcohols having from 6 to 22 carbon atoms, in either straight chain or branched chain configuration with ethyleneoxide, e.g., a tridecanol ethylene oxide condensation product having from 1 to 15 moles of ethylene oxide per mol of tridecanol. The mono- or dialkylphenol ethoxylates comprise the condensation product of a mono- or dialkylphenol wherein the alkyl group of the mono- or the alkyl groups of the dialkylphenol contains from 6 to 12 carbon atoms in either a straight or branched chain configuration with ethylene oxide, e.g., a nonylphenol ethylene oxide condensation product having from 8 to 25 moles of ethylene oxide per mole of nonylphenol, available commercially under the name Igepals. When not available commercially, the foregoing ethoxylates may be readily made by conventional reaction of ethylene oxide and the fatty alcohol or mono- or dialkylphenol compound. Generally speaking, anywhere from 1 to 100 moles, preferably 1 to 40 moles, of ethylene oxide may be reacted per mol of fatty alcohol or mono- or dialkylphenol, with the water solubility or dispersibility of the ethoxylate usually increasing as the number of moles of reacted ethylene oxide increases.

     The compounds of formula IV which are also utilized in preparing the instant compounds are also well known and are most often referred to by those skilled in the art as &#34;Polyalkylene ether glycols&#34;. They are sometimes known as polyalkylene glycols, polyalkylene oxide glycols, polyglycols or polyoxyalkylene diols. As indicated above, they may be represented by the formula HO--C a  H 2a  O b  H. In the polyoxyalkylene diols useful in this invention, a is an integer 2 to 6, preferably 2 or 3 and b is an integer 2 to 30, preferably 2 to 20, the simplest of which is diethylene glycol. Certain of the compounds of formula IV are available under the commercial name Carbowax and prepared by the addition of ethylene oxide to ethylene glycol, e.g., Carbowax 300 contains on average 6.4 moles of ethylene oxide per mole of glycol and Carbowax 600 contains on average 13.2 moles of ethylene oxide per mole of glycol. The compounds of formula IV which are not available commercially may be prepared by the addition of an alkylene oxide to a low molecular weight glycol, e.g., ethylene glycol, diethylene glycol, triethylene glycol, etc. Not all the hydrocarbylene radicals present need be the same. Polyoxyalkylene diols formed by the copolymerization of a mixture of different alkylene oxides or glycols may be used or the polyoxyalkylene diol may be derived from a cyclic ether such as dioxolane, which results in a product having the formula, 
     
         HO--C.sub.2 H.sub.4 OC.sub.2 H.sub.4 O).sub.b H 
    
     The hydrocarbylene radicals may be straight chain or may have a branched chain as in the compound known as polypropylene ether glycol, which has the formula, ##STR18## 
     As indicated above, the product derived from each of the various processes described above is hydrolyzed and, preferably, neutralized to yield the final ester product in salt form. 
     The hydrolysis, i.e., the preparation of the compounds of formula I in free acid form, is effected under mild, basic conditions, preferably employing an alkali or alkaline earth metal hydroxide, more preferably, an alkali metal hydroxide, e.g., sodium or potassium hydroxide. The hydrolysis may be carried out conveniently at a temperature of from -10° to 60° C., preferably, 10° to 30° C. 
     Neutralization is conveniently effected employing an alkali or alkaline earth metal hydroxide, ammonium hydroxide or by reaction with a mono-, di-, or tri-(C 2  -C 4 ) alkanol ammonium compound, a mono-, di-, tri- or tetra-(C 1  -C 4 ) alkylammonium compound, pyridine or morpholine. The neutralization may be carried out conveniently at a temperature of from -10° to 90° C., preferably, 10° to 30° C. 
     The most conspicuous property of the compounds of formula I is their great activity at surfaces and interfaces, making them especially useful as emulsifiers, surfactants, dispersants and lubricants. As a result, the possible applications of these new compounds are extremely varied. For instance, they can be used as wetting, frothing or washing agents in the treating and refining of textiles; for converting liquid or solid substances which per se are insoluble in water (such as hydrocarbons, higher alcohols, oils, fats, waxes and resins) into creamy emulsions, clear solutions or fine, stable dispersions; for carbonizing; for dyeing, e.g., in the pasting of dyestuffs, in dyeing acetate with insoluble dyestuffs, in the preparation of dyestuffs in finely divided form, etc.; for fulling, sizing, impregnating and bleaching treatments; as cleansing agents in hard water; in tanning and mordanting processes; as a means for improving the absorptive power of fibrous bodies; and as an aid in softening baths for hides and skins.

     EXAMPLE 15 
     Several representative compounds of the present invention were evaluated as foaming agents according to the following procedure: 
     Into a glass stoppered 500 cc. graduated cylinder is added 200 cc. of water and 1 cc. (conc.-5 g./1.) of the compound which is being evaluated as a foaming agent. After the cylinder is stoppered, it is held horizontally and shaken in the horizontal position for 5 cycles (10 times). After the shaking is completed, the cylinder is set on the bench and the stopper is removed. The average height of foam is then recorded (initial). As a measure of foam stability, the average height of foam is recorded after 1 minute and 5 minutes has elapsed. 
     The test is repeated employing 2.5 g./l. and 1.25 g./l. of the test compound. The results of this evaluation appear in Table 3 below.

     Several representative compounds of the present invention were also evaluated as dispersing agents by their ability to disperse titanium dioxide according to the following procedure: 
     To 50 g. of  6  TITANOX-RA NC in a beaker is added, sufficient water to form a stiff, slightly moist paste. This paste is Mix A, the system for which the Fluidity Point (amount of dispersant needed for initial dispersion) and the Concentration-Aggregation (C-A) Value (amount of dispersant needed to ensure that flocculation does not occur) is determined. The compound which is being evaluated as a dispersant is then added to Mix A in small increments with thorough but gentle mixing, until the pigment mass becomes fluid enough so that a spatula drawn through the mixture leaves no trail behind it. This system is Mix B. The concentration of dispersant added on a percent solids basis is the Fluidity Point. The pigment is now deflocculated and considered dispersed. 
     To 1 g. of  7  ACRYSOL GS is added 1 to 2 drops of Mix B and, after severe flocculation of the pigment system is noted, dropwise addition of Mix B is continued until the dispersed pigment absence of flocculation. The total amount of dispersant required to reach this point is recorded on a percent solids bases as the C-A value. The results of this evaluation appear in Table 5 below.

     EXAMPLE 18 
     Several representative compounds of the present invention were evaluated as detergents according to the following procedure: 
     Two solutions, one containing 25.0 g./l. of caustic flakes (as a control) and the other containing 25.0 g./l. of caustic flakes and 0.25 g. of the compound which is being evaluated as a detergent, are heated to boiling, after which time a cotton greige good swatch (1 3/4&#34;×1/4&#34;) is added to each solution. After 1 hour at a boil, the swatches are rinsed at boiling temperature, neutralized at room temperature and rinsed again at a boil. After the swatches are extracted and dried, they are suspended at room temperature for 5 minutes in a solution containing 1 g./500 cc. of  10  AZO Rhodine 2G Conc. after which time they are allowed to air dry in a vertical position. The amount of dye absorbed by the swatches, i.e., the creep or crawl of the dye, is then measured; the greater the creep, the better the detersive ability of the test compound. The results of this evaluation appear in Tables 6, 6A and 6B below.

     EXAMPLE 19 
     Several representative compounds of the present invention were evaluated as emulsifying agents by their ability to emulsify solvents according to the following procedure: 
     Three solutions, the first of which contains 6 cc. of water, 4 cc. of  11  Solvesso®150 and 0.5 g. of the compound which is being evaluated as an emulsifying agent, the second of which contains 6 cc. of water, 4 cc. of perchlorethylene and 0.5 g. of the compound which is being evaluated as an emulsifying agent, and the third of which contains 6 cc. of water, 4 cc. of  12  Varsol No. 1 and 0.5 g. of the compound which is being evaluated as an emulsifying agent, are mixed thoroughly and aged for 1 hour to allow for prewetting equilibrium, after which time the solutions are re-emulsified (by mixing) and 5 ml. of each are run into a  13  Bidwell-Sterling distilling receiver. The amount of separation of the two liquids is then measured at different time intervals; the less the separation, the better the emulsifying ability of the test compound. The results of this evaluation appear in Tables 7, 7A and 7B below.

     EXAMPLE 20 
     Several representative compounds of the present invention were evaluated as fiber finishing agents according to the following procedure: 
     The compound which is being evaluated as a fiber finishing agent is applied to polyester and polyamide filament and staple fiber yarn by the dip/centrifuge method in such a way that the uptake is 0.5% solids in each case. The dynamic yarn/steel friction (sliding friction) on the staple fiber yarn and the yarn/yarn friction (static friction) on the filament yarn is then measured employing a Rothschild &#34;F&#34; meter, which is a widely accepted control friction meter. As regards to the dynamic yarn/metal friction, the unit continuously electronically determines the differences in tension developed in a fiber on yarn by its passage over a pin of the other frictional surface or through a twist of the fiber around a pin. Instrument geometry is carefully controlled allowing internal calculation of &#34;f&#34;, the coefficient of friction. With respect to the yarn/yarn friction, the force &#34;p&#34; after the point of friction is expressed as a range representing the reduced tension as a result of the fact that the cohesive forces of the yarn are overcome by the presence of the fiber finishing agent on the yarn (slip) and the tension measured at a point where the cohesive forces of the yarn again dominate (stick). All of the friction measurements are conducted at 20° C. and 65% relative humidity. The results of this evaluation appear in Tables 8 and 8A below

     EXAMPLE 21 
     Several representative compounds of the present invention were evaluated as anti-static agents according to the following procedure: 
     The compound which is being evaluated as an anti-static agent is applied to polyester and polyamide staple fiber yarn by the dip/centrifuge method in such a way that the uptake is 0.5% solids in each case. The electrostatic behavior is then determined by measuring the discharge halftime in seconds employing a static voltmeter. All of the electrostatic measurements are conducted at 20° C. and at relative humidities of 30% and 65%, respectively. The results of this evaluation appear in Table 9 below.
