Abstract

A new environmental friendly catalyst,H4SiW6Mo6O40/PAn was prepared and used for synthesizing n-butyraldehyde 1,2-propanediol acetal.The influence factors of the synthesis were discussed and the best reaction conditions were found that the molar ratio of n-butyraldehyde to 1,2-propanediol is 1∶1.7,the amount of catalyst used is 1.0% of feed stocks,and the reaction time is 40 min.H4SiW6Mo6O40/PAn is an excellent catalyst for synthesizing n-butyraldehyde 1,2-propanediol acetal and the yield can reach over 78.5%.
