摘　　要：以脂肪族多元醇、苯甲酸为原料,以氢氧化钾为催化剂,二甲苯为带水剂,合成了3个多元醇苯甲酸酯增塑剂。考察了催化剂、带水剂及投料配比对反应的影响。得到优化的反应条件为:n(多元醇羟基):n(苯甲酸)=1.00:1.05,催化剂用量为1%,二甲苯为带水剂,210～220℃回流带水反应至基本无水带出,在该条件下产物收率为97.7%～99.1%。产物结构经FTIR、~1HNMR、UPLC-MASS确证。Polyol benzoate platiczer was synthesized by the reaction of polyol with benzoic acids using KOH as a catalyst and xylene as a water-carrying agent. Types of catalyst, water-carrying agent and different mole ratios of raw materials were selected to investigate their impacts on the resulted yield. The optimum synthesis condition was found as follows： The mole ratio of benzoic acid to polyol was 1.05 ： 1.00; the mass ratio of catalyst to benzoic acid was 1.0%; xylene was used as a water-carrying agent; the reaction temperature was 210 - 220℃; refluxed untill no water was taken out. Under the above conditions, the optimal esterification rate was 97.7 - 99.1% as a result. The structures of yielded compounds were confirmed by FTIR, ^1HNMR and UPLC-MASS.
