采用简单浸渍法制备了SnO2负载的磷钼杂多酸（PMo12/SnO2），并采用X-射线衍射和扫描电镜对其进行了表征。以PMo12/SnO2为催化剂，利用超声作用，快速合成了糠酸正丁酯并研究了其反应动力学。通过单因素实验法研究了各因素对糠酸正丁酯产率的影响，得出了最佳反应条件：醇酸物质的量比为3:1，催化剂0.50 g，带水剂5 mL，超声作用时间15 min，超声波功率200 W。在此条件下糠酸正丁酯的产率达到97.5%。与文献报道的其他方法相比，超声辅助PMo12/SnO2催化合成糠酸正丁酯具有需时少、产率高、能耗低等特点。测定了343 K、353 K和363 K时催化反应的动力学参数，结果表明糠酸正丁酯的超声辅助PMo12/SnO2催化合成反应符合二级动力学方程，其反应表观活化能为27.85 kJ/mol。与单纯超声酯化法、PMo12/SnO2催化酯化法、直接水浴加热酯化法相比，由于超声处理与PMo12/SnO2催化之间可能存在某种协同作用，超声辅助PMo12/SnO2催化合成法显著降低了酯化反应的表观活化能，促进了反应的快速进行，提高了糠酸正丁酯的产率。

SnO2-supported 12-molybdovanadophosphoric acid (PMo12/SnO2) was prepared by a simple impregnation method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). n-Butyl furoate was synthesized under ultrasound irradiation with PMo12/SnO2 as catalyst. Through single factor experiments, the effect of each factor on the yield of n-butyl furoate was investigated. The optimal reaction conditions were as follows: the molar ratio of butyl alcohol to furoic acid was 3:1; the amount of catalyst was 0.50 g; the volume of water-carrying agent was 5 mL; ultrasound irradiation time was 15 min; ultrasound irradiation power was 200 W. Under these conditions, the yield of n-butyl furoate reached 97.5%. Compared to other reported methods, this ultrasound-assisted synthesis of n-butyl furoate catalyzed by PMo12/SnO2 had advantages such as shorter reaction time, high yield, and low energy consumption. The kinetic parameters of the reaction at 343 K, 353 K, and 363 K were measured, and the results indicated that the ultrasound-assisted synthesis of n-butyl furoate catalyzed by PMo12/SnO2 followed second-order kinetics, with an apparent activation energy of 27.85 kJ/mol. Compared to simple ultrasound-assisted esterification, PMo12/SnO2-catalyzed esterification, and direct esterification in a hot water bath, the ultrasound-assisted synthesis catalyzed by PMo12/SnO2 significantly decreased the apparent activation energy of esterification, accelerated the catalytic reaction, and improved the yield of n-butyl furoate, owing to the potential synergistic effect between ultrasonic treatment and the catalytic action of PMo12/SnO2,.
