    Abstract: The invention relates to the preparation of aliphatic-aminonitriles by partial hydrogenation of aliphatic dinitriles atelevated temperature and higher pressure, in the presence of asolvent and catalyst. Catalyst, containing the following is used:(a) compound based on metal, e.g. nickel, cobalt, iron, rutheniumand rhodium; (b) from 0.01 to 25 wt.% promotor to component (a)based on metal such as palladium, platinum, iridium, osmium,copper, silver, gold, chromium, molybdenum, tungsten, manganese,rhenium, zinc, cadmium, lead, aluminium, tin, phosphorus, arsenic,antimony, bismith, silicon, titanium, zirconium and the rare earthelements, and (c) from 0 to 5 wt.% compound to component (a) basedon alkali or alkaliearth metal, provided that component (a) isdifferent from an iron-based compound or from iron, as well asfrom the metals cobalt, ruthenium or rhodium when component (b) ispromotor based on a metal from the group containing titanium,managanese, chromium and molybdenum. An additional condition isthat when component (a) is a compound based on ruthenium orrhodium separately, or of ruthenium and rhodium, or of nickel andrhodium, promotor (b) can optionally be dropped.

    Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst by a process which comprises using a catalyst which (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal. with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or rhodium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.
