| Abstract: | H4SiW12O40/ZrO2-Al2O3 was prepared by impregnation,and characterized by FT-IR and XRD.Catalytic activity of H4SiW12O40/ZrO2-Al2O3 was evaluated in the synthesis of cyclohexanone ethylene ketal.The different reaction parameters were discussed and the best reaction conditions were found out.Experimental results showed that H4SiW12O40/ZrO2-Al2O3 is an excellent catalyst.The optimum conditions are: molar ratio of ethylene glycol to cyclohexanone is 1.4∶ 1,the dosage of cat alyst is 1.5 % based on feed stocks and the reaction time is 7 5min,the yield of cyclohexanone ethylene ketal can reach 87.5%. |
