Abstract
In a process for the continuous hydrogenation of nitrites to primary amines in the liquid phase over a suspended, activated 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, the hydrogenation is carried out in the absence of ammonia and basic alkali metal compounds or alkaline earth metal compounds.
