摘　　要：用笔者研制的改性钛酸酯催化剂TAV—B,合成了苯多羧酸(DOP)型增塑剂,并确定了生产DOP的最佳工艺条件。过滤极容易;产品质量好,酸值低;不用氮气作保护。Benzene polycarboxylic acid ester(DOP) has been synthesised by using modified ti-tanate ester catalyst (TAC-B). The optimum process conditions were established. The characteristics are:easy filtering,high quality, low pH value and without nitrogen gas protection.
