摘要： Aromatic amines and iron oxide pigment are produced by reacting a ferrous salt, a reduceable aromatic nitrogen compound chosen from nitroderivatives with a single nitro-group or with two nitro-groups and azoderivatives, and a basic compound, chosen from hydroxides and carbonates of ammonium, alkali metals and alkaline earth metals, operating at 25.degree.-200.degree. C. in an aqueous medium. The color of the pigment can be varied from yellow to black by increasing the reaction temperature and the molar ratio between ferrous salt and aromatic nitrogen compound.
