摘　　要：研究了由对甲苯磺酸与氧化铜反应制得的对甲苯磺酸铜作为催化剂,合成丁酸异戊酯,其最佳反应条件为:醇酸物质的量比1.4∶1.0,反应时间1.5h,催化剂用量0.2%(以丁酸的物质的量计),反应温度120～140℃,酯化率达到99%以上.对甲苯磺酸铜制备容易,使用后处理简单,可以重复使用.Copper p-toluenesulfonate was prepared by the reaction of p-toluenesulfonic acid and copper oxide. As a catalyst, copper p-toluenesulfonate was used in the synthesis of isoamyl butyrate. The optimum reaction conditions were as follows：reaction time 1 .5 h, molar ratio of isoamylol and n-butyric acid 1.4：1, reaction temperature 120 - 140℃, catalyst 0.2 % （molar percent of n-butyric acid）, the yield was more than 99%. The preparation of copper p-toluenesulfonate was simple and there was no need of regeneration.
