摘　　要：首次以固载杂多酸盐TiSiW12O40/TiO2为多相催化剂，通过正丁酸和正戊醇反应合成了丁酸正戊酯，并探讨了诸因素对酯化率的影响。实验表明：TiSiW12O40/TiO2具有良好的催化活性，醇酸物质的量比为1.3：1，催化剂用量为反应物料总量的1.5%，反应时间1.0h，反应温度125-135℃，酯化率可达98.9%。The synthesis of n-amyl butyrate using TiSiW12O40/TiO2 as catalyst has been studied. The optimum conditions are: molar ratio of n-amyl to butyl acid is 1.3:1, the quantity of catalyst is equal to 1.5% feed stock, the reaction temperature is 125-135℃, and the reaction time is 1.0h. TiSiW12O40/TiO2 is an excellent catalyst for synthetizing n-amyl butyrate and its yield can reach over 98.9%.
