| Abstract: | Benzaldehyde 1,2-propanediol acetal was synthesized from benzaldehyde and 1,2-propanediol in the presence of SO2-4/TiO2WO3.The factors influencing the synthesis were discussed and the best condi tions were found out.The optimum conditions are: molar ratio of benzaldehyde to 1,2-propanediol is 1∶1.25,the quantity of catalyst is equal to 0.50% feed stock,and the reaction time is 50 min.SO2-4/TiO2-WO3 is an excellent catalyst for synthesizing benzaldehyde 1,2-propanediol acetal and its yield can reach over 81.7%. |
