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%.
Benzaldehyde 1,2-propanediol acetal was synthesized from benzaldehyde and 1,2-propanediol in the presence of SO42- / TiO2-MoO3-La2O3. These factors influencing the synthesis were discussed and the best conditions were found. 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%.
