Vanillin 1,2-propylene glycol acetal was synthesized using 1,2-propylene glycol and vanillin as starting materials, mesopore materials MCM-41 supported phosphotungstic acid hydrate as catalyst and cyclohexane as water stripping agent. Effects of factors on yield of product, such as molar ratio of the reactant, reaction time, the amount of water stripping agent and catalyst dosage and supported contents, were investigated. Exptl. results showed that the preferential conditions were as follows: the molar ratio of vanillin to 1,2-propylene glycol was 1:2.4; supported content was 50%, the dosage of catalyst was 2.0% of the total weight of the reactants; the amount of cyclohexane as water stripping agent was 15 mL; the reaction time was 2.0 h. Under these conditions, the yield can achieve 92%.
