| 摘 要： | 本文提出了用硫脲电化学制备二硫甲脒的新方法．采用具有隔膜的夹套Ｈ型三电极体系的电解池，工作电极为筒型铂网，辅助电级为铂片，饱和甘汞电极为参比电极，阳极区是含硫脲的稀硫酸溶液，辅助电极区只是稀硫酸，控制温度１０℃，工作电极电位控制在＋０．３Ｖ（ｖｓ．Ｓ．Ｃ．Ｅ．）电解制备了二硫甲脒．反应时间为７ｈ；产率３６．０％，电流效率２２．６％，研究表明工作电极电位０．３Ｖ时，硫脲开始缓慢电氧化，随即生成二硫甲脒．

| Abstract: | A new method for 1,1'-dithiodiformamidine prepared by the electrooxidation of thiourea is proposed.1,1'-dithiodiformamidine is produced using sandwich-H-type electrolytic cell with ionic exchange film, at temperature 10°C, in 1.0 mol·L-1 H2SO4 electrolytic solution containing thiourea and controlling working electrode potential at 0.3 V(vs, S.C.E).Pt net is used as working electrode,Pt plate conter electrode and S.C.E. reference electrode.The reaction thime is 7 hours.The produetivty and current efficiency are 36.0% and 22.6% ,respectively. |
