Abstract
H_3PW_6Mo_6O_40/PAn was used as catalyst for synthesizing benzaldehyde glycol acetal from benzaldehyde and glycol.Under the optimum conditions,that the molar ratio of benzaldehyde to glycol is 1/1.4,the mass ratio of the catalyst to the reactants is 0.8%,and the reaction time is 45 min,the yield of benzaldehyde glycol acetal is 79.0%.This catalyst has many advantages,such as low catalyst dosage,short reaction time,high activity and pollution-free to the environment.
