Catalytic Hydrogenation in Vapor Phase Using Urushibara Nickel as Catalyst

Catalytic hydrogenation in vapor phase with new types of Urushibara nickel catalyst was carried out. 1) New types of U–Ni were prepared from nickel chloride and aluminum. U–Ni–BA and U–Ni–AA were respectively obtained by treating the precipitated nickel with alkali or acetic acid. 2) These catalysts are quite easy to prepare and were proved to be useful for hydrogenation. Above all, U–Ni–AA is, the most convenient for vapor phase hydrogenation, since it was found to be highly active and the aluminum served as carrier. It was also used in hydrogenation in liquid phase.
