| Abstract: | Benzaldehyde 1,2-propanediol acetal was synthesized from benzaldehyde and 1,2-propanediol in the presence of SO42-/TiO2-MoO3. The factors influencing the synthesis werediscussed and the optimal conditions were found out. The optimum conditions are: molar ratio of benzaldehyde to 1,2-propanediol is 1: 1.1, the quantity of catalyst is equal to 0. 25% feed stock, and the reaction time is 50 min. SO42-/TiO2-MoO3 is an excellent catalyst for synthesizing benzaldehyde 1, 2-propanediol acetal and its yield can reach over 77.3%. |
