摘　　要：以苹果酸和正丁醇为原料,废弃的全氟磺酸树脂为催化剂,在微波辐射条件下合成苹果酸丁酯,对影响合成苹果酸丁酯的因素进行研究.结果表明:酸醇物质的量比为1∶5、催化剂用量0.7g、微波辐射时间25min、微波辐射功率400W时,苹果酸丁酯的最高产率可达90.9%.该催化剂绿色环保且易于回收,重复使用6次苹果酸丁酯的产率仍然可以达到78.6%.The dibutyl malate has been synthesized by malic acid and n-butyl alcohol, catalyzed by re- jected perfluorosulfonic acid resin under microwave irradiation, the author has also studied the effects of synthetic conditions. The results show that the ester yield is 90.9% under the optimum operation condi- tions：the molar ratio of malic acid to n-butyl alcohol is 1 ： 5,the amount of catalyst is 0.7 g, the reaction time is 25 min and power of microwave irradiation is 400 W. The catalyst is environment-friendly and easy to be recovered. The yield of dibutyl malate is still up to 78. 6% after the catalyst is used for the sixth time.
