Title: Synthesis of cyclohexanone glycol ketal catalyzed by Al-cross-linked montmorillonite
Abstract: The Al-cross-linked montmorillonite catalyst were prepared and characterized by means of XRD and BET.The catalyst was used for synthesizing cyclohexanone glycol ketal from cyclohexanone and glycol.The influence of catalyst dosage,the molar ratio of cyclohexanone to glycol,the amount of water carrying agent cyclohexane and reaction time on the product yield was studied.The experimental results showed that the Al-cross-linked montmorillonite had high catalytic activities.The optimum reaction condition was obtained as follows: n(cyclohexanone)∶n(glycol)=1∶1.5,reaction time 1 h,catalyst dosage 2% and the amount of water carrying agent 20% of tatal mass of the feed stock respectively.The yield of cyclohexanone glycol ketal reached 74.0% under the optimum reaction condition.
