摘要
报道了以丁二酸和无水乙醇为原料，在氯化亚锡催化下合成丁二酸二乙酯，并研了 反应条件。结果表明：在回流温度下，醇酸物质的量比为２．３：１，催化剂用量为０．００３ ｍｏｌ／ｍｏｌ 丁二酸时，反应３．５ ｈ，丁二酸的转化率可达７７．３％。
Diethyl succinate is synthesized from succinic acid and absolute alcohol over stannous chloride catalyst, and reaction conditions are studied. At reflux temperatures, when ratio of alcohol to acid is 2. 3:1, catalyst is 0. 003 mol /mol succinic acid, reaction time is 3. 5 h, conversion of diethyl succinate can reach 77. 3%.
