| Abstract: | Cyclohexanone-1,2-propanediol ketal was synthesized from cyclohexanone and 1,2-propanediol in the presence of ammonium ceric sulfate. The factors influencing the synthesis were discussed and the best conditions were found out. The optimum conditions are:molar ratio of cyclohexanone to 1,2-propanediol is 1∶1.5, the quantity of catalyst is equal to 1.4% of feed stocks, the volume of cyclohexane as the water-carrying agent is 12 mL and the reaction time is 60 min. Ammonium ceric sulfate is an excellent catalyst for synthesizing cyclohexanone-1,2-propanediol ketal with yield of 65.9%. |
