摘　　要：使用了Aspen Plus11.1模拟正丁醇与乙酸反应精馏生成乙酸正丁酯的反应精馏过程,对进料温度、回流比和进料位置进行了优化分析,得到了最佳工艺参数:进料温度常温;回流比为1;进料位置为第六块塔板。另外,模拟得到了反应精馏塔的温度和浓度分布,为指导乙酸正丁酯的工业生产提供了理论参考。The distillation of n-butyl acetate from butanol and acetic acid was simulated by Aspen Plus 11.1.The feed temperature, reflux ratio and feed stage were optimized and analyzed. The best parameters were obtained,feed temperature is room temperature, the reflux ratio is 1, and feed stage is stage 6th. The temperature and con-centration distribution of reactive-distillation column provided theory reference for the production of n-butyl acetate.
