摘要 以己二酸二乙酯为原料,在微波辐射下经Dieckmann缩合反应合成2′-羰环戊基甲酸乙酯。研究了反应时间、反应温度、催化剂用量等因素对反应产率的影响,并通过正交设计优选了2′-羰环戊基甲酸乙酯的合成条件。结果表明,各试验因素的影响效能为反应温度(反应时间(催化剂用量;最佳合成条件为反应温度90℃,反应时间50 min,催化剂与原料的摩尔比为1.1∶1,在此条件下,常压合成目标物的产率可以达到99.5%。 Orthogonal test was performed to examine the influences of reaction conditions on microwave-assisted synthesis of 2'-oxo-cyclopentanecarboxylic acid ethyl ester from diethyl adipate. The results showed that the influence order of three factors is: reaction temperature 〉 reaction time 〉 catalyst dosage. The optimal conditions were found as follows: reaction temperature 90 ℃, reaction time 50 min, the molar ratio of catalyst to diethyl adipate 1.1 : 1, providing 99.5% yield.
