| 摘 要： | 采用微波辐射技术，利用颗粒状活性炭固栽对甲苯磺酸作催化剂，由柠檬酸和正丁醇直接酯化合成柠檬酸三丁酯。实验结果最佳反应条件：微波辐射功率为550W，醇酸物质摩尔比为3．9：1，反应时间50min，w（催化剂）=4％，柠檬酸的转化率达95．2％。反应速率明显高于常规加热方式。

| Abstract: | Tributyl citrate was synthesized of p-toluenesulfonic acid supported on granule activated carbon under microwave irradiation.The experiment results showed that when power of microwave irradiation was 550 W, trihydric acid is 3.9:1(mol),and catalyzer's weight is 4% based on the total mass of initial materials,reaction time was 50 min.Conversion of citric acid amounts to 95.2%.Additionally,it was found that under microwave irradiation,the reaction rate of esterification and yield of the product was higher than that of conventional heating method. |
