Summary:The present invention describes an improved catalyst and process for the selective hydrogenation of nitro aromatics, nitrosoaromatics and aromatic hydroxyl amines to their corresponding amines using gaseous hydrogen, in the presence of soluble iron compounds as a catalyst and optionally other reducible groups. L'invention concerne un catalyseur amélioré et un procédé d'hydrogénation sélective d'aromatiques nitro, de nitrosoaromatiques et d'hydroxylamines aromatiques en amines correspondantes de ceux-ci au moyen d'hydrogène gazeux, en présence de composés de fer solubles utilisés en tant que catalyseurs et éventuellement d'autres groupes réductibles.
