摘　　要：研究了以甲苯为原料绿色间接电合成苯甲醛的方法,并得出最佳反应条件为:将二氧化锰在650℃时灼烧成以三氧化二锰,以Mn3+为氧化剂,反应温度55℃,硫酸浓度7.5mol/L,将甲苯氧化生成苯甲醛,该过程采用电合成法生产苯甲醛。克服了化学合成法中的缺点,生产过程污染少,反应条件温和,产率高。Benzaldehyde is an important material in fine industry. Benzaldehyde is green indirect electrosynthesized by toluene and Mn^3＋ in acidic solutions. The best reaction condition is that the manganese dioxide is transformed into manganese sesqnioxide at 650℃, then Mn^3＋ as the oxidant, and the toluene is oxidated to the benzaldehyde at 55℃ when the concentration of H2SO4 is 7.5mol/1. The method is achieved by electrosynthesizing in warm condition, gaining higher ratio of products and avoiding chemical pollution.
