Abstract: Butyraldehyde 1,2-propanediol acetal was synthesized from butyraldehyde and 1,2-propanediol catalyzed by solid superacid SO42-/TiO2-MoO3. The experimental results showed that catalytic activity of the catalyst was improved through addition of MoO3 into SO42-/TiO2. Influencing factors of the synthesis were discussed and the optimums reaction condition was found to be: molar ratio of butyraldehyde to 1,2-propanediol 1:1.5, dosage of catalyst 0.5% of feed stocks, and reaction time 45 min. SO42-/TiO2-MoO3 is an excellent catalyst for synthesizing butyraldehyde 1,2-propanediol acetal to improve the yield up to 87.5%.
Key words: butyraldehyde 1, 2-propanediol acetal, solid superacid, acetalization
