| description | Preparation of aromatic amines, preferably tolylenediamine, comprises catalytic hydrogenation of nitro compounds, preferably dinitrotoluene in the presence of hydrogenation catalyst with an active component mixture containing platinum, nickel and an additional metal on a substrate. Independent claims are included for: (1) catalyst for the preparation of aromatic amines, comprising hydrogenation catalyst with an active component mixture containing platinum, nickel and an additional metal on a substrate; and (2) the preparation of hydrogenation catalyst, comprising mixing the substrate with an aqueous solutions of at least platinum salt, nickel salt and copper salt, cobalt, iron, zinc, manganese or chromium; evaporating the water; adding water-soluble basic compound; and reducing the produced catalyst with hydrogen. |
