摘　　要：以Mn(II) /Mn(III)为氧化还原媒质 ,间接电氧化合成了邻、间、对位甲基苯甲醛 .在电解和合成的过程中 ,分别施加了超声进行反应 .实验结果表明 ,电解的电流效率和邻甲基苯甲醛、间甲基苯甲醛的合成产率在超声的参与下有 10 %左右的提高 .优化了超声电解的条件 ,并探讨了超声与未超声时将二甲苯的三个异构体氧化为相应醛的难易程度 .o-, m-, p-Methylbenzaldehydes were synthesized from dimethylbenzene with Mn(II)/ Mn(III) as the oxidant by indirect electrooxidation. Ultrasound was used in the process of electrolysis. The experimental results indicated that the current efficiency of electrolysis and, the yields of o- I m-, p-methylbenzaldehydes were promoted about 10% under ultrasound irradiation. The conditions of ultrasound electrooxidation were optimized.
