摘要
Wells-dawson type heteropolyacid catalyst was prepared by acidification-etherization and characterized by FTIR,over which cyclohexanone ethylene ketal was synthesized from cyclohexanone to ethylene.The experiment results showed that the optimal reaction conditions are as follows:the amount of Cyclohexanone is 0.1mol,the molar ratio of Cyclohexanone to ethylene was1.0/1.5(mol/mol),catalyst amount 1.50%(pencent of the reaction stock materials).Through reaction time 2.5h,the yield of cyclohexanone ethylene katal reached over 95.0%.
Abstract：WeUs-dawson type heteropolyaeid catalyst was prepared by acidification-etherization and characterized by FTIR, over which cyclohexanone ethylene ketal was synthesized from cydohexanone to ethylene. The experiment results showed that the optimal reaction conditions are as follows：the amount of Cyclohexanone is 0.1mol, the molar ratio of Cyclohexanone to ethylene was1.0/1. 5 （mol/mol）, catalyst amount 1.50% （pencent of the reaction stock materials）. Through reaction time 2.5h, the yield of cyclohexanone ethylene katal reached over 95.0%.
