摘　　要：以己酸和乙醇为原料 ,采用强酸性阳离子交换树脂催化合成己酸乙酯 ,研究了影响反应的因素和催化剂的重复使用性能。在 0 .1mol己酸 ,0 .6mol无水乙醇 ,1.2g催化剂 ,回流分水 1.2h的反应条件下 ,酯化率达 89.5 %。催化剂重复使用 6次后 ,产率降至 75 .6 %。In this paper, with caproic acid and ethanol, the synthesis of ethyl caproate were studied by strong acid cation exchange resin catalyst, the influent factors of reaction and the reuse ability of the catalyst were investigated. When 0.1mol caproic acid,0.6mol ethanol and 1.2g of resin were refluxed and water segregated for 1.2h,the yield of dibutyl succinate was 89.5%,while the catalyst is reused for 6 times, the yield is down to 75.6%.
