| 摘 要： | 以固载杂多酸盐TiSiW12O40/TiO2为多相催化剂，通过肉桂酸和正丁醇反应合成了肉桂酸正丁酯。探讨了TiSiW12O40/TiO2对酯化反应的催化活性，考察了醇酸摩尔比、催化剂用量、反应时间等因素对酯收率的影响。实验表明：TiSiW12O40/TiO2是合成肉桂酸正丁酯的良好催化剂，在醇酸摩尔比为4：1、催化剂用量为反应物料总质量的2％、反应时间1．5h、反应温度122～126℃的最佳条件下，肉桂酸正丁酯的收率可达93．33％。

| Abstract: | n -Butyl cinnamate was synthesized from cinnamic acid and n -butyl alcohol using TiSiW12O40/TiO2 as catalyst. The catalytic activity of TiSiW12O40/TiO2 on the esterification was discussed. And the factors influencing the yield of the product were investigated. The experimental results showed that TiSiW12O40/TiO2 was an excellent catalyst for synthetizing n - butyl cinnamate and the yield could reach over 93.33% under the optimum conditions as follows： molar ratio of n - butyl alcohol to cinnamic acid 4 ： 1, the quantity of catalyst 2% （base on the total of feed stock）, reaction time 1.5 h,and reaction temperature 122 - 126℃. |
