Methyl acetate has been synthesized by the reaction between acetic acid and methanol in an experimental batch reactor. The reaction has been carried out homogeneously without using any catalyst and heterogeneously by using Amberlyst 16 resin catalyst. The reaction is performed using different temperatures in the range of 318.15-333.15 K. The reaction catalyzed by Amberlyst 16 is found faster than the uncatalyzed reaction and the influence of process parameters such as catalyst loading, reaction mixture temperature, initial reactant mole ratio, catalyst size, agitation speed on acetic acid conversion has been investigated experimentally for the catalyzed reaction. Further, pseudo-homogeneous kinetic models have been developed for the catalyzed reaction and the uncatalyzed reaction. The reaction rate expressions of catalyzed reaction and uncatalyzed reaction are used to derive the reaction rate equation influenced by the catalyst alone. This rate equation is useful to examine the influence of catalyst alone in the heterogeneously catalyzed methanol esterification reaction.

Amberlyst 16树脂酯化过程的动力学建模和模拟研究

乙酸甲酯是通过在实验间歇反应器中乙酸和甲醇之间的反应合成的。该反应已在不使用任何催化剂的情况下进行了均相，并在使用Amberlyst 16树脂催化剂的情况下进行了非均相。反应是在318.15-333.15 K范围内的不同温度下进行的。发现由Amberlyst 16催化的反应比未催化的反应快，并且工艺参数如催化剂负载量，反应混合物温度，初始反应物摩尔比，催化剂的影响也更快。对于催化反应，已经通过实验研究了粒径，搅拌速度对乙酸转化率的影响。此外，已经为催化反应和未催化反应开发了伪均相动力学模型。用催化反应和未催化反应的反应速率表达式来推导单独受催化剂影响的反应速率方程。该速率方程可用于检验催化剂在非均相催化的甲醇酯化反应中的影响。
