中文摘要：

研究了柠檬酸与正丁醇在Ce（SO4）2·4H2O/NH2SO3H复配催化剂催化作用下制备柠檬酸三丁酯的工艺条件。实验结果表明Ce（SO4）2·4H2O/NH2SO3H催化合成柠檬酸三丁酯的最佳反应条件为：醇酸摩尔比为4.0∶1,催化剂用量为1.5%（以柠檬酸质量计）,m[Ce（SO4）2·4H2O]∶m（NH2SO3H）=2∶1,反应温度为150℃,反应时间为7h,酯化率〉98.5%,精制后产品纯度〉99.5%。

英文摘要：

The technical condition of synthesis tributyl citrate by citric acid and butanol, with Ce（SO4）2·4H2O/NH2SO3H as catalyst was studied. The optimum reaction conditions of esterification were determined as follows： molar ratio of butanol to citric acid 4.0 ： 1, amount of catalyst 1.5% （based on the mass of citric acid）, m[Ce（SOn）2·4H2O] ： m（NH2SO3H）=2 ： 1, reaction temperature 150℃, reaction time 7h, esterification yield could be up to 98.5%, and the purity of tributyl citrate was over 99.5%.
