应用反应精馏法生产高纯度醋酸甲酯的实验研究Ⅱ.半连续反应精馏

Experimental Study on Production of High Purity Methyl Acetate via Reactive Distillation

以醋酸和甲醇为原料,应用半连续反应精馏法生产高纯度醋酸甲酯,并对影响产品纯度的几个主要参效及操作条件(包括催化剂浓度、醋酸和甲醇的摩尔比、进料速率、回流比)进行了探讨。

This paper presents the experimental results of producing high purity methyl acetate via the reaction of methanol and acetate acid, by using the method of semi-continuous reactive distillation. The main factors and the suitable operating conditions: the catalyst concentration, HOAc/MeOH mole ratio、feed flow rate and reflux ratio, which affect the purity of product, are discussed in this paper.
