采用硫酸高铈为催化剂合成了丙酸异丁酯。系统考察了催化剂用量、醇酸物质的量比、反应时间、带水剂种类和用量以及催化剂重复使用性等因素对收率的影响。适宜反应条件为:丙酸0.1mol,醇酸物质的量比为1.3,催化剂0.8g,环己烷5mL,反应40min,收率可达96.4%。 Isobutyl propionate was synthesized by using cerium sulfate as catalyst. The effect of catalyst amount, alkalinity ratio, reaction time, the type and amount of water-carrying agent and the reusability of catalyst on the yield were systematically investigated. The suitable reaction conditions are: propionic acid 0.1mol, alkyd ratio 1.3, catalyst 0.8g, cyclohexane 5mL, reaction 40min, the yield can reach 96.4%.
