| Abstract: | Cyclohexanone ethylene ketal was synthesized from cyclohexanone and ethylene glycol in the presence of solid superacid S2O2-8/SnO2-SiO2.The effect of molar ratio of cyclohexanone to ethylene glycol,catalyst amount,reaction time,and amount of the water-entraining agent on the ketalization reacation were investigated.The optimum conditions were that molar ratio of cyclohexanone to ethylene glycol was 1:1.5,cyclo-hexane as water-entraining agent,the quantity of catalyst was equal to 0.5% of feed stocks,and the reaction time was 1.5 h.S2O2-8/SnO2-SiO2 was a good catalyst for synthesizing cyclohexanone ethylene ketal and its yied can reach 86.9%. |
