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．
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.
