摘要
在一水硫酸氢钠存在下 ,由乙醇和丁二酸合成了丁二酸二乙酯。当丁二酸、乙醇和硫酸氢钠的物质的量比为 1∶ 6∶ 0 .2 ,环己烷为溶剂 ,回流分水 5 0 m in,酯收率达 80 .5 %
Diethyl succinate was synthesized with ethyl alcohol and succinic acid in the presence of sodium bisulfate monohydrate. When the ratio of succinic acid, ethyl alcohol and sodium bisulfate were 1∶6∶0.2, cyclehexane as solvent and water segregating for 50 min, the yield of the esterification was 80.5%.
