摘要
The'electrochemical reduction characteristics of α-nitronaphthalene in sulfuric acidsolution were first reported in this paper. The results showed that the 1-amino-5-naphthol can beprepared by electrodeduction from α-nitronaphthalene and reduction peak corresponding to thereaction of α-nitronaphthalene to 1-amino-3-naphthol was in the range of -0.40~0.60V(vs, D.H.E )on the amalgamated copper cathode in the presence of SnCl2 additives. The mechanism of α-nitronaphthalene electroreduction to 1-amino-5-naphthol was also investigated, the overallelectroreduction reaction was composed of two intermediate steps and two intermediate productsexisted in solution. The electrochemical reduction mechanism was similar to that of nitrobenzeneto para-aminophenol.
