Synthesis of cyclohexanone ethylene ketal using H_3PW_6Mo_6O_(40)/TiO_2-WO_3 as catalyst

Yang Shui-ji

Abstract

A new environmental friendly catalyst,H3PW6Mo6O40/TiO2-WO3was prepared with the impregnation method,and characterized by FT-IR and XRD.Cyclohexanone ethylene ketal was synthesized from cyclohexanone and glycol using H3PW6Mo6O40/TiO2-WO3as the catalyst.The influence factors on the yield of cyclohexanone ethylene ketal were also discussed.The optimum conditions were indentified:molar ratio of cyclohexanone and glycol is 1∶ 1.4,mass fraction of catalyst to reactants is 1.0%,cyclohexane dosage is 6 mL and reaction time is 60 minutes.The yield of cyclohexanone ethylene ketal can reach 84.5% under the optimum conditions.
