针对对苯二甲酸（PTA）和新戊二醇（NPG）合成聚对苯二甲酸戊二酯（PPT）出现的问题，应用PRO／II化工模拟软件对间歇反应精馏过程进行模拟优化，模拟结果与实际生产数据相吻合，相对误差在0．29％～7．85％之间；提出了减少塔顶馏出液中新戊二醇含量、精馏时间的工艺优化方案：以该工艺优化方案为依据对生产装置改造，改造后与改造前相比，精馏时间缩短了2．92h。

Batch reactive distillation process was simulated by using the PRO/II software. The relative deviation of component content of NPG, water in tower top and distillation time were 4.02 %, 7.85 % and 0.29 % comparing with the production data respectively. The process optimization cases were proposed, compared with the original production data with the optimum proposal, distillation time could be shortened by 2.92 h.
