Two Ni–MgO systems were synthesized and characterized as nickel catalysts for the hydrogenation of 1, 6-hexanedinitrile (adiponitrile) in the gas phase. The activity results were compared with those obtained for a commercial Raney–Ni. All three catalysts showed high selectivity to 1, 6-hexanediamine, for a total conversion with a maximum of 96% for the Ni–MgO catalyst, which was made from a NiO–MgO solution. However, only Ni–MgO ...
