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.

Abstract: The invention relates to a method for producing aliphatic alpha-omega amino nitriles in the presence of a catalyst composed of (a) iron or an iron based compound or a mixture thereof (b) 0.01 to 5 wt. %, in relation to (a), a promoter based on 2, 3, 4, or 5 elements selected from the group comprising aluminum, silicon, zirconium, titanium, and vanadium, and (C) to 0.5 wt. % in relation to (a) a compound based on an alkaline metal or alkaline-earth metal. The inventive method is characterized in that the aliphatic alpha-omega dinitrile contains 1.0 ppm or more phosphorus. Catalysts are obtainable through the reductive and optional successive passivation of magnetite, whereby the catalysts have a BET surface of 3 to 10 m2/g, a total pore volume of 0.05 to 0.2 ml/g, an average pore diameter of 0.03 to 0.1 mm and a pore volume portion in the range of 0.01 to 0.1 mm of 50 to 70%.
