  • Patent number: 5789621
    Abstract: A process for preparing an NH.sub.2 -containing compound by hydrogenating a compound containing at least one unsaturated carbon-nitrogen bond with hydrogen in the presence of a catalyst at temperatures not below room temperature and elevated hydrogen partial pressure in the presence or absence of a solvent which process includes the following steps:a) using a catalyst comprising a cobalt- and/or iron-containing catalyst, andb) after the conversion based on the compound to be hydrogenated and/or the selectivity based on the desired product has or have dropped below a defined value or the amount of an unwanted by-product has risen beyond a defined value, interrupting the hydrogenation by stopping the feed of the compound to be hydrogenated and of the solvent, if used,c) treating the catalyst at from 150.degree. to 400.degree. C. with hydrogen using a hydrogen pressure within the range from 0.
