a process is disclosed for recycling of polyester used in the fabrication of molded plastic goods , such as films , carbonated beverage bottles and particularly waste poly bottle grade , manufacturing residues and other manufactured articles . the process comprises the alcoholysis of washed or cleaned , crushed or grinded pet in one step of reaction , with alcohols containing from 1 to 4 carbon atoms in their molecule , in an autoclave reactor capable to support pressures of about 10 mpa and operating temperatures in the range of 10 to 300 ° c . ; followed by one or several steps of reaction product purification such as crystallization and / or centrifugation and / or distillation . the alcoholysis reaction product is a dialkyl aromatic ester , which is recovered by filtration or centrifugation and depending on the alcohol used in the process the daae obtained are several industrial products such as dimethyl terephthalate , dibutyl terephthalate , etc . from the daae it is possible to obtain , through a transesterification reaction , plasticizers as dioctyl terephthalate and through a hydrolysis reaction , a pure terephthalic acid . from the process mother liquor it is possible to recover through distillation the pure process - alcohol and ethylene glycol and / or other different industrial glycols that were forming the pet molecules , and an industriallizable distillation residue .
