在液镓电极上反丁烯二腈的电氢化二聚

Electrohydrodimerization of Fumarodinitrile on Gallium from Aqueous Media

  • 摘要: 在液镓电极上反丁烯二腈(FND)的电氢化二聚(EHD)不仅能在含离子型表面活性剂如四乙替对甲苯磺酸铵(TEA-PTS)溶液中发生,同样也能在含低浓度的强表面活性剂如TritonX-100溶液中进行。在不含有机表面活性剂的溶液中,FDN在滴镓电极上产生一个2电子还原波,生成名为丁二腈的饱和单体。在水溶液中加入一定浓度的TEA-PTS或低浓度的TritonX-100时,原来的2电子还原波分裂成两个连续的单电子还原波,生成相应的电氢化二聚物。

     

    Abstract: Electrohydrodimerization (EHD) of fumarodinitrile (FDN)on Gallium takes place not only from hydrotropic solutions of tetraethylammonium p toluenesulphonate (TEA PTS),but also from entrirely aqueous solution containing very low concentrations (say 10-1~10-3 mol·L-1) of strong surfactants,such as TritonX 100.In aqueous solution,not containing organic surfactants,FDN yields a single two electron reduction wave to the corresponding saturated (RH 2).Progressive additions of surfactants,the original two electron wave is splitted into two consecutire single electron reduction wave and the EHD of fumarodinitrile is obtained.
