摘要
以丁二酸酐、无水乙醇、氯化亚砜为原料合成丁二酸单乙酯酰氯。最佳工艺条件为:m(丁二酸酐)∶m(乙醇)∶m(氯化亚砜)=1∶0.56∶1.6;酯化反应时间2h,反应温度90℃;酰氯化反应时间5h,反应温度55~60℃。产品收率达89%以上。
Ethyl succinyl chloride was synthesized with succinic anhydride,alcohol and thionyl chloride as raw materials. The optimum condition was : m (succinic anhydnide)∶ m (alcohol)∶ m (thionyl chloride)=1∶0.56∶1.6;esterification reaction time,2h;temperature,90℃;acidylation reaction time,5h;temperature,55~60℃. The yield was over 89%.
