摘　　要：应用离子交换膜法电解邻氯硝基苯合成2,2′-二氯氢化偶氮苯.讨论了电极活化条件、电流密度、电解液温度等因素对电解还原反应的影响.结果表明:在反应温度t=80℃,阴极、阳极电解液分别为10%和30%(by m ass)的NaOH溶液,电流密度4.2A/dm2条件下电解,电流效率最高,可达73%,收率为83%.Using an ion exchange membrane as a separator, the 2,2′-Dichlorohydrazobenzene is synthesized by the electrolytic reduction of o-chloronetrobenzene . The effects of electrode activation condition, current density, electrolyte temperature on electrolytic reduction are discussed. It was found that the optimum reaction temperature is 80 ℃. When the electrolyte concentration was 30% NaOH at the anode and 10% NaOH at the cathode, current density is 4.2A/dm^2, the current efficiency reached 73% and yield is 83%.
