Abstract: The invention concerns a process for simultaneously preparing 6- aminocapronitrile and hexamethylene diamine proceeding from a mixture which contains a phosphorated compound and substantially adipodinitrile and is obtained by reacting butadiene with hydrocyanic acid in the presence of a catalyst containing a phosphorated compound. The process is characterized in that: (1) the portion by weight of a phosphorated compound, calculated as phosphorus, in the mixture is reduced ; (2) the resultant mixture is partially hydrogenated in the presence of a catalyst in order to form an alpha-, omega aminonitrile; and ( 3) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture.

Abstract: The invention concerns a method of simultaneously producing 6- aminocapronitrile (ACN) and hexamethylenediamine (HMD) by reacting adipodinitrile (ADN) with hydrogen in the presence of a catalyst containing nickel, at a temperature not below room temperature and at an elevated hydrogen partial pressure, optionally in the presence of a solvent. If the yield, based on the amount of ADN consumed, and/or the selectivity, based on the amount of ACN produced, drop(s) below a defined value, a) the reaction of ADN with hydrogen is interrupted by stopping the feed of ADN and, if present, also the solvent; b ) the catalyst is treated with hydrogen at a temperature in the range 150 to 400 .degree.C, using a hydrogen pressure of 0.1 to 30 MPa and a treatment time of 2 to 48 h; and c) the hydrogenation is subsequently continued using the catalyst treated in stage (b).

Abstract: Alkines, dienes, and/or singly unsaturated hydrocarbons; compounds containing sulphur, arsenic and/or antimony; oxygen, hydrogen and/or carbon monoxide are removed from material flows in a total of at most three process steps. In a first process step, after hydrogen has been added to the feed material flow at a hydrogenation catalyst which is largely resistant to compounds containing sulphur, arsenic and/or antimony, alkines, dienes and/or singly unsaturated hydrocarbons are removed by hydrogenation, oxygen which may optionally be present also being at least partially removed by hydrogenation. In a second process step, compounds containing sulphur, arsenic and/or antimony and/or residual oxygen from the first process step are removed by absorption on a contact mass, and/or residual oxygen, carbon monoxide and/or residual hydrogen are at least partially converted catalytically into water and carbon dioxide. Optionally, in a third process step, residual carbon monoxide and/or residual hydrogen from the preceding process steps is/are converted on a contact mass into carbon dioxide and/or water.
