【Abstract】 A new kind of solid acid based on heteropolyacid proved be a useful catalyst in the synthesis of cyclohexyl formate.The new catalyst HPAS/TiO₂-WO₃ was based on heteropolyacid supported on mixed metal oxides bymicrowave and ultrasonic method. The catalyst was characterized through TEM,TG-DTA,and IR. Data show that catalyst is very active in synthesis reaction of cyclohexyl formate even at mild temperature. Under optimal conditions,the yield of cyclohexyl formate was about 85.4%.更多还原
