| Abstract: | Benzaldehyde glycol acetal was solvent-free synthesized from benzaldehyde and glycol with iodine as catalyst under microwave irradiation.The effects of microwave irradiation power, microwave irradiation time, reactant ratio,and amount of catalyst on the yield of benzaldehyde glycol acetal were studied.The results showed that the optimum reaction conditions are as follows：microwave irradiation power was 259 W,reaction time was 6.0 min,the molar ratio of benzaldehyde and glycol was 1：1.8 and amount of iodine was 2.5% ,the yield was up to 86.7%. |
