| Abstract: | Cyclohexanone 1,2-Propanediol ketal was synthesized by using K2Cr207 modified coal acitve carbon as catalyst. The optimum reaction conditions were as follows： the molar ratio of Cyclohexanone to 1,2-Propanediol was 1：2.0 （mol/mol）, the quantity of catalyst equaled to 2.9% of feed stocks,the volume of Cyclohexane was 8.0 mL, the reaction time was 4.0 h （based on 0.05 mol Cyclohexanone）. The yield of product was 92.7%. The results of tests showed that the catalyst had higher catalytic activity to the reaction. |
