Abstract: The invention relates to a method for simultaneous preparation of 6-aminocapronitrile and hexamethylene diamine from adipodinitrile, comprising the following steps: a) hydrogenating adipodinitrile in the presence of a catalyst containing an element of the eight subgroup as catalytically active component to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers; b) separating by distillation hexamethylene diamine from the mixture containing 6-aminocapronitrile, hexamethylene diamine, adipodinitrile and high boilers and c1) separating by distillation 6-aminocapronitrile and subsequently d1) separating by distillation adipodinitrile or c2) simultaneously separating by distillation 6-aminocapronitrile and adipodinitrile into separate fractions. The method is characterized in that the temperature of the bottom in steps d1) or c2) is below 185 DEG C.

Abstract: A process for preparing an NH2-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, and b) 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 DEG to 400 DEG C. with hydrogen using a hydrogen pressure within the range from 0.1 to 30 MPa and a treatment time within the range from 2 to 48 h, and d) subsequently continuing the hydrogenation of the compound containing at least one unsaturated carbon-nitrogen bond.
