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: The invention concerns the production of compounds containing NH2-groups by hydrogenating compounds containing at least one unsaturated carbon-nitrogen bond with hydrogen in the presence of a catalyst at temperatures not below room temperature and under increased hydrogen partial-pressure, preferably in the presence of a solvent, in which one (a) uses a cobalt and/or ironcontaining catalyst, and (b), after conversion of the compound to be hydrogenated and/or the selectivity of the product desired drops below a defined value, or after an increase in the quantity of an undesired by-product beyond a defined value, one breaks off the hydrogenation by stopping the supply of the compounds to be hydrogenated and, if desired, of any solvents present, (c) one treats the catalyst with hydrogen at a temperature between 150 to 400 ~C and a hydrogen pressure between 0.1 to 30 MPa and selects a treatment time of 2 to 48 hours, and (d) one subsequently continues the hydrogenation of a least one compound containing an unsaturated carbonnitrogen bond as well as the regeneration of cobalt and/or iron-containing catalysts.
