Title: Catalyzed Synthesis of Cyclohexanone Ethylene Ketal
Abstract: Cyclohexanone ethylene ketal was synthesized from cyclohexanone and ethylene glycol in the presence of La/SO_4~(2-)/C, and factors affecting the reaction were discussed including molar ratio of cyclohexanone to ethylene glycol, amount of catalyst and reaction time. The optimal condition was molar ratio of cyclohexanone to ethylene glycol with 1∶1.5, 1.5% of catalyst, cyclohexane as water-entraining agent, reaction at 108~ 120℃ for 60 min, and the yield of cyclohexanone ethylene ketal could be reach to over 90.6%.
