摘要
本研究对生产偏酐所产生的母液中含有的芳香族羧酸加以回收，用于生产混合酯增塑剂。芳香族羧酸回收率＞７５％，制得的混合酯增塑剂总体指标优于邻苯二甲酸二（２－乙基己醇）酯。
This study focused on the recovery of aromatic polycarboxylic acids from the mother liquor of manufacturing trimellitic anhydride and it's application for making mixed plastifier. The recovery retio of aromatic polycarboxylic acids was more than 75% and the total function of the plastifier was better than DOP.
