Abstract: Benzaldehyde ethylene glycol acetal was directly synthesized from benzaldehyde and ethylene glycol under microwave irradiation with cupric sulfate as catalyst.The effects of microwave irradiation power,microwave irradiation time,reactant ratio,amount of catalyst,amount of water-carrying agent cyclohexane on the yield of benzaldehyde ethylene glycol acetal were studied. The results showed that the most suitable conditions for the reaction are as follows:microwave irradiation power is 600 W,irradiation time is 12 min,benzaldehyde 0.075 mol,ethylene glycol 0.112 5 mol,the amount of cupric sulfate is 1.2 g,the amount of cyclohexane is 12 mL,and the yield is up to 77.9%.

Key words: benzaldehyde ethylene glycol acetal, microwave irradiation, cupric sulfate
