Catalytic synthesis of cyclohexanone 1, 2 propanediol ketal with modified coal active carbon catalyst

The synthesis of cyclohexanone 1, 2 propanediol ketal using modified coal active carbon as the catalyst was carried out. The influences of reaction conditions were also investigated. The optimum reaction conditions were: based on 0.1 molar cyclohexanone, the molar rate of cyclohexanone to 1,2 propanediol ketal 1:1.5,the amount of catalyst 2.4% (based on the mass of total materials) ,The volume of cyclohexane was 9. 0mL, the reaction time 2h. On the conditions, the yield of the product was 85.9% and the catalyst showed high activity.
