摘　　要：采用超声波法制备了纳米固载杂多酸盐催化剂HPAS/TiO2 WO3和HPAS/TiO2 MoO3,考查了其红外光谱及TEM ,并在丙酸环己酯的合成中试验了其催化性能。实验表明 ,制备的催化剂具有良好的催化活性 ,丙酸环己酯的产率可达 77.4%。Supported nanoheteropolyacid salt catalyst HPAS/TiO 2 WO 3 and HPAS/TiO 2 MoO 3 was prepared by a supersonic method. The catalytic action of the catalyst was investigated in synthesizing process of cyclohexyl propanoate. Results show that these catalysts are of high activity than other and its yield can reach over 77%.
