摘　　要：以NKC-9为催化剂,以无水乙醇和癸二酸为原料,通过酯化反应合成了癸二酸二乙酯。研究了带水剂用量、醇酸摩尔比、催化剂用量和转速等因素对产率的影响。实验表明:无水乙醇与癸二酸的摩尔比为8∶1,催化剂NKC-9的用量为2.0 g,带水剂环己烷的用量为20 m L,转速为500 r/min,酯化产率为93.5%。The synthesis technology of diethyl sebacate was optimized from sebacic acid and ethyl alcohol using NKC-9 as catalyst. The effects of the amount of water carrier, molar ratio of alcohol to acid, the amount of catalyst and agitation rate were studied on the yield. The experimental results showed that the molar ratio of ethyl alcohol to sebacic acid was 8∶1, the amount of catalyst was 2. 0 g, the amount of catalyst was 20 mL, the agitation rate was 500 r/min, the yield of the product was 93. 5%.
