Abstract:
A method of producing a primary amine by the hydrogenation of a nitrile in the presence of a hydrogenation catalyst. The hydrogenation catalyst contains at least one metal selected from the group consisting of nickel, cobalt and iron. Before use in the hydrogenation of nitrile, the hydrogenation catalyst is pretreated with at least one treating agent selected from the group consisting of hydrocarbons, alcohols, ethers, esters and carbon monoxide at 150 to 500° C.
