摘　　要：以乙酸和环己醇为原料,采用纳米固载型杂多酸HPA/TiO2-WO3为催化剂,系统研究了合成乙酸环己酯的优化条件.优化条件为:乙酸0 108mol,环己醇0 06mol,催化剂0 3g,反应时间90min,乙酸环己酯收率为84 7%.The supported nanograde heteropolyacid catalysts HPA/TiO_2-WO_3 was prepared by a supersonic method for the synthesis of cyclohexyl acetate.Factors influencing the yield wear systematically investigated.Thus,0.10mole acetic acid,0.18 mole cyclohexyl and 0.3g catalyst reacted at 104～120℃ for 1.5h to give the ester in 84.7 yield.
