The vanillin 1, 2 - propylene glycol acetal was synthesized by the reaction of vanillin and 1, 2-propylene glycol using sodium bisulfate as catalyst under microwave irradiation. Factors influencing the reaction, such as different mole ratio of materials, catalyst amounts, microwave irradiation power and time, were discussed. The optimal synthetic technology was obtained as follows： n （1, 2 - propylene glycol）： n （vanillin） = 2.2, irradiation power 500 W, irradiation time 10 rain, NariS04 3.0 g/mol （ based on the amount of vanillin）, 20ml cyclohexane to give in 68.2% yield.
