摘　　要：利用醋酸甲酯水解体系热力学、水解反应动力学以及催化填料的基础数据,采用化工流程模拟与分析的方法,系统地对醋酸甲酯催化精馏水解过程进行了模拟研究。通过与实验数据进行对比,验证了该模拟方法的正确性。通过对工艺条件的灵敏度分析,获得该过程较优的工艺参数。在对现有工艺流程模拟的基础上,结合工业实际操作,提出两种工艺改进方案。The basic data of thermodynamics,kinetics and catalytic packing are used in this thesis to simulating the process of methyl acetate hydrolysis via catalytic distillation by the method of chemical engineering process simulation and analysis.By comparing the simulation results and experimental results,the correctness of the mathematical model is also validated.The feeding position of methyl acetate and water from overhead,the ratio of water to methyl acetate in feed and the ratio of top reflux to feed methyl acetate ranges are obtained by the tool of sensitivity analysis of software.Two new processes for hydrolysis of methyl acetate were proposed on the basic of the process simulation and industrial practice.
