Abstract
Synthetic method of cyclohexanone Ethylene Glycol Ketal was investigated using activated carbon supported phosphotungstic acid.The effec ts of reaction time and temperature,ratio of reactants,quantity and stability of catalyst were examined.Results showed that the yield was over 94.8% under optim um conditions. It proves that the activated carbon supported phosphotungstic aci d is a high active catalyst for ketalization and can be reused.
