摘　　要：本文研究了以甲苯为原料,采用成对电解合成方法,进行阴极和阳极同时间接电氧化制取苯甲醛。当选用钛基镀铂电极及钒与锰氧化还原电对时,成对电合成苯甲醛的总电流效率达179.5％。还研究了添加CTAB对化学氧化速度的影响,以及外加H_2O_2对阴极电合成选择性的影响。Indirect electrooxidation of toluene to benzaldehyde simultaneously in the cathodic and anodic compartment of a cell has been studied. In conditions of using platinum plating electrodes, using V(Ⅴ)/V(Ⅳ) and Ma(Ⅲ)/Mn(Ⅱ) as cathodic and anodic redox couples,the maximum total current efficiency for benzaldehyde production is 179.5%. The effect of additive CTAB on chemical oxidation rates and the effect of externally added H_2O_2 on selectivity of cathodic electrosynthesis have been investigated.
