HYDROGENATION OF NITRILE INTO PRIMARY AMINE, METHOD FOR PRODUCING RANEY CATALYST, AND RANEY CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for mildly hydrogenating a nitrile, by which a primary amine can be produced in high selectivity and by which a secondary reaction such as the dissociation of the nitrile can be avoided. SOLUTION: This method for hydrogenating the nitrile into the primary amine comprises hydrogenating the nitrile over an activated, -Al2O3-containing, macroporous Raney catalyst based on an alloy of aluminum and at least one transition metal selected from the group consisting of iron, cobalt and nickel, and, if desired, one or more further transition metals selected from the group consisting of titanium, zirconium, chromium, and manganese.
