Received Date: 10 January 1999

The electrochemical reduction characteristics of α-nitronaphthalene in sulfuric acid solution were first reported in this paper.The results showed that the 1-amino-5-naphthol can be prepared by electrodeduction from α-nitronaphthalene and reduction peak corresponding to the reaction of α-nitronaphthalene to 1-amino-5-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 overall electroreduction reaction was composed of two intermediate steps and two intermediate products existed in solution.The electrochemical reduction mechanism was similar to that of nitrobenzene to para-aminophenol.
