  The invention is directed to a process for preparing a terephthalic acid di-ester. The process includes contacting terephthalic acid with a C 6 -C 10 alcohol in the presence of an organo-titanium catalyst and an alcohol-amine promoter under conditions effective to form a corresponding terephthalic acid di-ester. The promoter can improve the reaction time by as much as 50%.

  该发明涉及一种制备对苯二甲酸二酯的过程。该过程包括在有机钛催化剂和醇胺促进剂的存在下，将对苯二甲酸与C6-C10醇接触，以有效形成相应的对苯二甲酸二酯。促进剂可以将反应时间提高多达50%。

  Terephthalic acid di-alkyl esters in which the alkyl groups of the ester are obtained from branched C5 to C13 alcohols or mixtures of mixtures of C5 to C13 linear and branched alcohols in which less than 50 mole % of the alcohols are linear alcohols and the branched chain alkyl groups of such alcohols contain methyl groups and have an average of more than 7 carbon atoms and are free of ethyl groups. The di-esters are particularly useful as plasticizers and particularly plasticizers for polyvinyl chloride.

  苯二甲酸二烷基酯，其中酯的烷基来自于支链C5到C13醇或混合物，其中不到50摩尔％的醇为直链醇，这些醇的支链烷基含有甲基，平均含有超过7个碳原子并且不含乙基基团。这些二酯尤其适用于增塑剂，特别是聚氯乙烯的增塑剂。
