| Abstract: | The batch esterification reaction between the p-phthalic acid(PTA) and 1,4-butylene glycol(BDO) by using the tetra-n-butyl titanate as catalyst were investigated and the neumocystis moisture tester,gas chromatograph and automatic potentiometric titrator were used to analysis the samples of distillate and esterification solid from the reaction process.In this work the influencing factors of esterification reaction and the reaction’s degree,such as the temperature,catalyst amount,raw material ratio and other factors were researched to get the optimum conditions of the batch esterification reaction.The obtained data will provided the base for optimization of industrial continuous process. |
