Electrochemical reduction of nitrobenzene has been studied at different solvents and pH values. It was found if pH is low, reduction to amine will result, but at high pH, hydroxylamine would be the final product. The case of reduction has been related to proton availability and it is .shown how In aqueous media, E1/2 of reduction changes with pH values.In nonaqueous media, however, similar results are obtained by just the addition of an acid to the aprotic solvent. With an optimum electrochemical system, a large scale electrolysis of nitrobenzene to aniline will be accompanied with more than 85% yield as well as a short time of electrolysis. It is hard to achieve these standards by chemical methods.
