| 摘 要： | 在超声波槽中电生成纳米金属氧化物,继而以MnO2/Mn2 或金属氧化物氧化还原电对作为媒介,电催化氧化合成苯甲醛.实验表明,电流效率和苯甲醛的产率在超声的参与下有明显的提高,优化了超声电解的条件.在较高温度下反应时,有利于提高生成苯甲醛的电流效率.反应选择性较高,苯甲醛产率可达88.9%.

| Abstract: | Benzaldehyde was synthesized from benzaldealcohol using MnO2/Mn2 or PbO2/Pb2 ,Ce4 / Ce3 ,Cr2O72-/Cr3 as the oxidant by indirect electrooxidation.Ultrasound was used in the electrolysis process.The experimental results indicated that the current efficiency of electrolysis and the yields of benzaldehyde were promoted under ultrasound irradiation.The increasing of reaction temperature enhanced both of the reaction rate for benzahyde and current efficiency.Yield of benzaldehyde was up to 88.9%. |
