摘要：

A new environmental friendly catalyst, H4SiW6Mo6O40/PAn was prepared. Cyclohexanone 1,2-propanediol ketal was synthesized from cyclohexanone and 1,2-propanediol in the presence of H4SiW6Mo6O40/PAn. The factors influencing the synthesis were discussed and the optimum conditions were found out. Molar ratio of cyclohexanone to 1,2-propanediol is 1:1.7, catalyst content is equal to 1.0% feed stock, and the reaction time is 1.0 h. H4SiW6Mo6O40/PAn is an excellent catalyst for synthesizing cyclohexanone 1,2-propanediol ketal and its yield can reach over 84.6%.
