Abstract: A process for preparing caprolactam by cyclization of 6-aminocapronitrile in the presence of water at elevated temperature and in the presence or absence of a catalyst and a solvent, comprises a) removing from the cyclization reaction effluent ("reaction effluent I") caprolactam and all components boiling higher than caprolactam ("high boilers"), b) treating the high boilers of stage a) with phosphoric acid and/or polyphosphoric acid at from 200 to 350 DEG C. to obtain a reaction effluent II, and c) removing caprolactam formed and any 6-aminocapronitrile from reaction effluent II of stage b) to obtain separation from unconverted high boilers and acid used.

Abstract: The invention concerns a method of simultaneously producing 6aminocapronitrile (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 ~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: 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.
