N2 - Electrosynthesis of 1,5-diaminonaphthalene from 1,5-dinitronaphthalene was studied. At room temperature, the electrochemical reduction behavior of 1,5-dinitronaphathlene has been studied on a Cu electrode by cycle voltammertry in DMF-water solution. It was an irreversible reaction controlled by diffusion. 1,5-Dinitronaphthalene exhibited two successive waves in the DMF-water solution which were corresponding to the two nitro-group electroreduction. The transfer coefficients of the reaction were calculated. The values of α1 and α2 were between 0.275-0.335 and 0.360-0.437, respectively. Influence of electrolysis potential (E), the concentration of 1,5-dinitronaphthalene (c1), the concentration of sulfuric acid (c2), the passed charge (Q) and volume ratio of solvent to water (Y) was investigated to optimize the electrolytic conditions, with the maximal yield to be 77%.
