| 摘 要： | 以甲烷磺酸铜为催化剂合成丁酸苄酯,考察了催化剂用量、反应时间、醇酸物质的量比对酯化率的影响。实验表明:丁酸0.167 mol,醇酸物质的量比1.2:1,甲烷磺酸铜用量0.125％(基于丁酸的摩尔分数),反应时间2.0~2.5 h,环己烷5 mL作带水剂,在回流温度下酯化率可达96.9％;与其它几种Lewis酸相比,甲烷磺酸铜具有较高的催化活性,反应后易与产物分离,催化剂重复使用8次,酯化率仍达到94.5％以上。

| Abstract: | Copper methanesulfonate is used as catalyst in esterification of benzyl alcohol with butyric acid. The amount of catalyst, reaction time and the molar ratio of alcohol to acid have been investigated. The esterification yield reaches to 96. 9% under the conditions of 0. 167 mol butyric acid, 1. 2 :1 molar ratio of benzyl alcohol to butyric acid, 0. 125% catalyst (based on the molar percent of butyric acid) , 1. 5 - 2. 0 h reaction time, 5 mL cyclohexane as water-carrying agent and at refluxing temperature. Compared with other Lewis acids, copper methanesulfonate exhibits higher esterification yield. After being recycled 8 times, the esterification yield of copper methanesulfonate is still above 94. 5%. |
