Dawson型磷钨钒杂多酸催化合成环己酮乙二醇缩酮
Sythesis of Cyclohexanone Ethylene Ketal Over wells-Dawson type TungstenVanadophoric Heteropolyacid
【Abstract】 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%.
