摘要：
A new environmental friendly catalyst, H4SiW12O40/PAn was prepared and identified by means of FT-IR, XRD and TG/DTA. Cyclohexanone 1,2-propanediol ketal was synthesized from cyclohexanone and 1,2-propanediol in the presence of H4SiW12O40/PAn. 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 1:1.4, the quantity of catalyst is equal to 1.0% of feed stocks, and the reaction time is 40 min. H4SiW12O40/PAn is an excellent catalyst for synthesizing cyclohexanone 1,2-propanediol ketal and its yield can reach over 96.5%.
