| titleOfInvention | A kind of ester composition and preparation method thereof from PTA substandard goods |
| abstract | This application involves a kind of ester compositions and preparation method thereof for being originated from p-phthalic acid (PTA) substandard goods.The present processes are related in the presence of composite catalyst, make p-phthalic acid's residue, binary acid, cell alcohol and dihydric alcohol be reacted to obtain ester composition by one-step method.Composite catalyst inhibits the esterification of cell alcohol and unit acid, so that gained ester composition is mainly the mixture for the ester that the ester that monohydric alcohol and binary acid are formed and dihydric alcohol and monoacid are formed.The preparation method process of the application is few, and process is simple, realizes and very recycles PTA residue, and prepared ester composition can be used as environment-friendly plasticizer, and effect and dioctyl terephthalate (DOTP) are suitable. |
