以环己烷为夹带剂反应精馏合成丙酸丙酯的模拟研究

Simulation study on synthesis of N-propyl propionate in reactive distillation with cyclonexane as entrainer

使用工程软件Aspen Plus对以环己烷为夹带剂的反应共沸精馏合成丙酸丙酯的过程进行模拟,并优化了工艺流程。结果表明,当反应精馏塔的操作条件为精馏段6块板,反应段和提馏段都为7块板时,塔釜产品丙酸丙酯的摩尔质量分数高达99.41%。

Synthesis of n-propyl propionate（PROPRO） in reactive distillation with cyclohexane （CYH） as entrainer is simulated and optimized by Aspen Plus. The results show that the molar fraction of PROPRO in the bottom of reactive distillation is 99. 41% when the rectifying section has six stages, and the reaction section and stripping section both have seven stages.
