| Abstract: | Benzaldehyde 1,2 -propanediol acetal was synthesized from benzaldehyde and 1,2 -propanediol in the presence of SO42-/TiO2 - MoO3 - La2O3. The factors influencing the synthesis were discussed and the best conditions were found out. The optimum conditions are: molar ratio of benzaldehyde to 1,2 - propanediol is 1: 1.8, the quantity of catalyst is equal to 1.0% feed stock, and the reaction time is 1.0 h. SO42-/TiO2 -MoO3 -La2O3 is an excellent catalyst for synthesizing benzaldehyde 1,2 - propanediol acetal and its yield can reach over 77.2%. |
