摘要：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 prence of a catalyst at temperatures not below room temperature and under incread hydrogen partial-pressure, preferably in the prence of a solvent, in which one (a) us a cobalt and/or iron-containing catalyst, and (b), after conversion of the compound to be hydrogenated and/or the lectivity of the product desired drops below a defined value, or after an increa 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 prent, (c) one treats the catalyst with hydrogen at a temperature between 150 to 400 DEG C and a hydrogen pressure between 0.1 to 30 MPa and lects a treatment time of 2 to 48 hours, and (d) one subquently continues the hydrogenation of a least one compound containing an unsaturated carbon-nitrogen bond as well as the regeneration of cobalt and/or iron-containing catalysts.
