ABSTRACT:
A process for the production of an aromatic hydrazo compound, which comprises catalytically reducing an aromatic nitro compound with hydrogen in an alkali metal hydroxide aqueous solution and a hydrogen-donating solvent in the presence of a noble metal catalyst and a quinoid compound cocatalyst at a high temperature under a high pressure, the hydrogen-donating solvent being a cyclic hydrocarbon in which hydrogen atoms are attached to its basic skeleton having 1 to 4 aromatic rings and at least one unsaturated carbon-carbon bond remains.
