Title: Synthesis of benzaldehyde 1,2-propanediol acetal catalyzed by SO_4~(2-)/TiO_2-MoO_3 solid superacid
Abstract: Benzaldehyde 1,2-propanediol acetal was synthesized from benzaldehyde and 1,2-propanediol in the presence of SO_4~(2-)/TiO_2-MoO_3. The factors influencing the synthesis were discussed 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. SO_4~(2-)/TiO_2-MoO_3 is an excellent catalyst for synthesizing benzaldehyde 1,2-propanediol acetal and its yield can reach over( 77.3%.)
