摘要
The ketalization of cyclohexanone with ethylene glycol catalyzed by I2 was studied.The effects of reaction time,reactant ratio,catalyst amount and the amount of water-carrying agent on the yield of cyclohexanone ethylene glycol ketal was investigated.The results showed that the most suitable condition for the reaction were as follows:ethylene glyco:cyclohexanone molar ratio 1.2,molar ratio of catalyst to reactant 0.005%,cyclohexane as the water-carrying agent 6 ml,reaction time 30 min.The yield was up to 94.3%.
