Nitrated aromatic compounds are continuously catalytically hydrogenated into their corresponding aromatic amines in the presence of an effective amount of a nickel or nickel/aluminum catalyst, the nickel catalyst being essentially devoid of aluminum values and the nickel/aluminum catalyst containing up to 5.5% by weight of aluminum values; the subject hydrogenation is thus conducted under conditions such as to limit the formation of nickel aluminates and the nickel or nickel/aluminum catalyst is continuously catalytically active for at least three days.
