Abstract: Nitrite is hydrogenated to primary amine using an activated macroporous Raney catalyst comprising alpha -alumina and transition metal(s), obtained by (i) shaping kneadable composition comprising an alloy, a shaping aid, water and a pore former, (ii) calcining and activating by treating with aqueous alkali metal hydroxide solution and (iii) rinsing with aqueous alkali metal hydroxide solution and water. Hydrogenating nitrite to primary amine involves using activated macroporous Raney catalyst comprising alpha -alumina and transition metal(s), such as iron, cobalt, nickel, titanium, zirconium, chromium and manganese. The Raney catalyst is obtained by preparing a kneadable composition comprising an alloy, a shaping aid, water and a pore former, which is then shaped to form a component. The shaped component is calcined and activated by treating with aqueous alkali metal hydroxide solution. The catalyst obtained is rinsed with aqueous alkali metal hydroxide solution and water. Independent claims are also included for the following: (1) a macroporous Raney catalyst; and (2) the production of a macroporous Raney catalyst.
