Title: Catalytic synthesis of n-butyraldehyde 1,2-propanediol acetal over H_4SiW_(12)O_(40)-PAn
Abstract: A new environmental friendly catalyst, H_4SiW_(12)O_(40)-PAn was prepared and used for n-butyraldehyde 1,2-propanediol acetal synthesis from n-butyraldehyde and 1,2-propanediol. 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∶1.5, the amount of catalyst used is 1.2% of feed stocks, and the reaction time is (1.0 h). H_4SiW_(12)O_(40)-PAn is an excellent catalyst for synthesizing n-butyraldehyde 1,2-propanediol acetal and the yield can reach over 95.2%.
