催化水解醋酸甲酯的动力学

The Macroscopic Kinetics of the Hydrolysis of Methyl Acetate Catalyzed by Cation Exchange Resin

摘要: 采用G—6104型阳离子交换树脂为催化剂，于间歇搅拌反应釜中测得了消除外扩散影响的醋酸甲酯水解反应速率数据，归纳得到了实验条件下阳离子交换树脂催化水解醋酸甲脂的动力学方程式。结果表明反应过程控制步骤是吸附在催化剂表面的醋酸甲酯同未吸附的水发生表面反应。催化剂用量和水酯摩尔比为醋酸甲酯水解率的重要影响因素。

Abstract: The macroscopic kinetics of hydrolysis of MeOAc, catalyzed by G - 6104 cation exchange resin, was measured in a stirred batch reactor. The rate determining step is surface reaction between adsorbed molecules of methyl acetate and unadsorbed molecules of w
