摘要/Abstract

摘要：用无水硫酸铜作催化剂，在微波辐射下催化合成苯甲醛乙二醇缩醛.系统考察微波辐射功率、微波辐射时间、原料配比、催化剂用量、带水剂用量对产率的影响.实验结果表明：当微波输出功率为600 W，辐射时间为12 min，苯甲醛用量为0.075 mol，乙二醇用量为0.112 5 mol，无水硫酸铜用量为1.2 g，带水剂环己烷用量为12 mL时，产率可达77.9%.

关键词： 苯甲醛乙二醇缩醛, 微波辐射, 无水硫酸铜

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
