| 摘 要： | 本文采用离子交换膜法合成3,3’-二氯联苯胺盐酸盐。研究了电解温度、阳极电解液浓度和用回收电解液对反应电流效率和产率的影响。结果表明：反应条件为t=80℃，阳极电解液浓度为30%（质量分数），阴极电解液浓度为10%（质量分数）时，电流效率最高，可达到93%，收率达到90%；还原反应所用的电解液，经简单处理后均可以回收使用，几乎不影响相应的实验结果。

| Abstract: | 3,3’-dichlorobenzidine hydrochloride was synthesized by using Ion Exchange Membrane. Some factors affecting on current efficiency and yield were discussed. It shows that the better reaction temperature is 80℃；When the electrolyte concentration was 30% at anode and 10% at cathode, the current efficiency could be up to 93% and yield was 90%. Furthermore, the same result could be attained when use the recycled electrolyte. |
