Abstract

Process for preparing aromatic diamine compounds by catalytic hydrogenation of the corresponding aromatic dinitro compound, in the presence of a solvent of said aromatic polynitro compound and in the presence of Raney nickel catalyst, characterized by hydrogenating the dinitro aromatic compound in the presence of sufficient Raney nickel catalyst to provide a concentration of Raney nickel catalyst of at least about 15% by weight of the aromatic dinitro compound to be hydrogenated.
