摘要

以硫酸为催化剂

测定了丙酸和甲醇反应体系在不同温度下(313 K～343 K)

不同催化剂含量下[0.5％～3％(w)]的常压液相反应动力学

得出了上述条件下的反应速率常数表达式.采用1％～2％(w)的硫酸为催化剂

测定了丙酸和甲醇酯化反应体系常压下化学反应相平衡数据.对所测得的相平衡数据用化学计量法进行了关联和推算

精度较好.

Abstract

The kinetics for the reactive system of propanoic acid and methanol was investigated over a temperature range 313 K-343 K under ambient pressure

and in the presence of the catalyst of sulfuric acid (0.5%-3% mass concentration). Chemical and vapor- liquid equilibria for the esterification system containing propanoic and methyl propionate with sulfuric acid (l%-2% mass concentration ) as catalyst were measured. Experimental results were correlated and estimated with good accuracy by using the stoichiometric approach.
