摘要/Abstract

摘要：用水合硫酸铁作催化剂，以丙酸和环己醇为原料，在微波辐射条件下，合成了丙酸环己酯.系统考察了微波辐射功率、辐射时间、醇酸物质的量比、带水剂用量、催化剂用量等因素对酯化率的影响.研究表明反应的最佳条件为：微波辐射功率700 W，固定丙酸用量0.05 mol，醇酸物质的量比为3∶1，水合硫酸铁用量为1.5 g，带水剂环己烷用量为6 mL，反应30 min后酯化率达94.4%.

关键词： 微波辐射, 水合硫酸铁, 丙酸环己酯

Abstract: Cyclohexyl Propionate was directly synthesized by propionic acid and cyclohexanol with ferric sulfate hydrate as the catalyst under microwave irradiation.The effects of microwave irradiation power,irradiation time,reactant ratio,amount of catalyst and amount of watercarrying agent on the yield of cyclohexyl propionate were systematically studied.Research results showed that the optimum reaction conditions were as follows:microwave irradiation power was 700 W,fixed amount of propionic acid was 0.05 mol,the ratio of cyclohexanol to propionic acid was 3∶1,the amount of catalysts was 1.5 g,and cyclohexane as the water-carrying agent was 6 mL,after 30 min reaction,the yield of cyclohexyl propionate reached 94.4%.

Key words: microwave irradiation, ferric sulfate hydrate, cyclohexyl propionate
