The electrochemical dissolution of magnesium 99.97 Mg and AZ-21 Magnesium alloy h.e.r. on magnesium electrochemical reduction of nitrobenzene, nitrosobenzene, phenylhydroxylamine, and meta-dinitrobenzene and the electrochemical oxidation of nitrobenzene and phenylhydroxylamine in MgClO42, NH4ClO4, NH42HPO4, and NH4ClO4--NH42 HPO4 have been investigated. The data indicate that the open circuit potential of magnesium in these electrolytes is determined by the mixed process of hydrogen evolution and magnesium dissolution. A-size Mg2MMgClO42 sat. with MgOH2-Chloro-2,4-dinitrobenzene, MgSat. NH4ClO4--NH42HPO4meta-dinitrobenzene and MgO.1OM NH4ClO4-O.45M NH42HPO4meta-dinitrobenzene cells were fabricated. The magnesium perchlorate electrolyte-1-chloro-2,4-dinitrobenzene cell yielded very promising results. An open circuit voltage of 1.4 -1.6 volts and an energy density of 30 w-hlb were obtained. The other cells were unsatisfactory. From the electrochemical data and the results of the fabricated cells it appeared that the meta-dinitrobenzene cathode material must be electrochemically reduced from the solvated state. Author
