根据实验数据建立了ＰＴＡ半连续酯化反应动力学模型，求得酯化反应活化能为２７３．７ｋＪ／ｍｏｌ．并对半连续酯化过程的影响因素进行了讨论．
Based on the experimental data, a kinetic model of semi-continuous esterification of PTA was established, and the activation energy of esterification reaction was found to be 273.7 kJ / mol. The influencing factors of semi-continuous esterification process are also discussed.
