摘要: 在液镓电极上,反丁烯二腈(FDN)的电氢化二聚(EHD)不仅能在含离子型表面活性剂如四乙基对甲苯磺酸铵(TEA_PTS)溶液中发生,同样也能在含低浓度的强表面活性剂如TritonX_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 on liquid gallium electrode can take place not only in hydrotropic solution of tetraethylammonium p_toluenesulphonate(TEA_PTS), but also in aqueous solution containing low concentration of strong surfactants, such as TritonX_100. In solution without organic surfactant, FDN yields a single two_electron reduction wave corresponding to the formation of a saturated monomer called as butanedinitrile. If some TEA_PTS or TritonX_100 is added into the solution, the original two_electron wave is splitted into two continuous single_electron reduction wave and corresponding EHD of fumarodinitrile is obtained.
