Abstract

Catalytic activities of H3PW6Mo6O40 in synthesizing n-butyraldehyde 1,2-propanediol acetal were reported. Various factors concerned in the reaction were investigated. The optimum conditions: the molar ratio of n-butyraldehyde to 1,2-propanediol is 1∶1.6,the mass ratio of the catalyst is 0.6% of all the reactants,volume of cyclohexane as the water-carrying agent is 8 mL,and the reaction time is 45min. Under these conditions,the yield of n-butyraldehyde 1,2-propanediol acetal is 80.5%.
