【摘要】 对合成顺丁烯二酸二异辛酯进行了研究，其中包括从众多催化剂中确定ＳｎＯ为反应催化剂，确定了反应的最佳条件，即催化剂用量为醇酐总重的１．５％，醇酐摩尔比为３∶１，反应时间２ｈ，反应温度为回流温度。最后，在最佳反应条件下，顺丁烯二酸酐的转化率达９９．８％。更多还原

【Abstract】 In this paper, the reaction of synthesizing di(2-ethyl hexyl) maleate from 2-ethyl hexanol and maleic anhydride was studied. SnO was founded having high catalytic activity by comparative experiments. The best reaction condition was determined, that is, the weight of catalyst was 3% of the overall weight of alcohol and anhydride, the molar ratio of alcohol with anhydride was 31 and the reaction time was 2h. At last 99.8% anhydride could be converted into product under this condition.更多还原
