| 摘 要： | 四氯化锡能代替硫酸作为酯化催化剂。在五水四氯化锡催化下,由丁二酸和正丁醇合成了丁二酸二丁酯,研究了反应的影响因素。当丁二酸、正丁醇和四氯化锡的物质的量之比为1∶8∶0.114时,回流分水60min,酯收率可达93.9%。同时利用四氯化锡催化合成了癸二酸二丁酯、己二酸二丁酯和马来酸二丁酯。

| Abstract: | Stannic Chloride can be used as catalyst for esterification instead of sulphuric acid. The synthesis of dibutyl succinate with succinic acid and n butyl alcohol as reactants and pentahydrate stannic chloride as catalyst has been studied. The yield of the ester could reach 93 9% under molar ratio of succinic acid, n butyl alcohol and stannic chloride were 1∶8∶0 114, refluxing and water segregating for 60 min. The dibutyl sebacate, dibutyl adipate and dibutyl maleate were also synthesis with stannic chloride pentahydrate as catalyst. |
