The way of catalytic hydrogenation of aromatic nitro compounds in solution or melt in the presence of water and at least one catalyst of the relative metal, at which the catalytic amount is at least one of the compounds of vanadium. vanadium oxides at levels 0, II, III, IV or V. The amount of vanadium compound compounds is usually reduced to <1%. The method does not produce azo compound or an azoxyl compound. Hydrogenation, especially on horseback, is faster than this. |
