| titleOfInvention | Novel catalyst and its use in preparing aliphatic alpha, omega-aminonitriles |
| abstract | Aliphatic alpha, omega-aminonitriles are prepared in the presence of a catalyst which contains (a) iron or a compound based on iron or a mixture thereof, (b) from 0.01 to 5% by weight, based on (a), of a promoter based on 2, 3, 4 or 5 elements selected from a group consisting of aluminum, silicon, zirconium, titanium and vanadium and (c) from 0 to 0.5% by weight, based on (a), of a compound based on an alkali metal or alkaline earth metal, by a process in which the aliphatic alpha, omega-dinitrile used contains 1.0 ppm by weight of more of phosphorus. Catalysts are obtainable by the reduction and, if required, subsequent passivation of a magnetite, the catalysts having a BET surface area of from 3 to 10 m<2>/g, with a total pore volume of from 0.05 to 0.2 ml/g, an average pore diameter of from 0.03 to 0.1 mum and a pore volume fraction of from 50 to 70% in the range of from 0.01 to 0.1 mum. |
