Continuous hydrogenation of nitrites to primary amines over activated Raney catalyst, involves hydrogenating nitrites in absence of ammonia and basic alkali or alkaline earth metal compounds

摘要

A continuous hydrogenation of nitrites to primary amines, in a liquid phase over a suspended, activated Raney catalyst, involves hydrogenation in absence of ammonia and basic alkali or alkaline earth metal compounds. The Raney catalyst is produced from an aluminum alloy and transition metal(s) selected from a group comprising iron, cobalt, nickel, titanium, zirconium, chromium, and manganese.
