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: Producing 3-pentenonitrile comprises isomerizing a 2-methyl-3-butenonitrile feed stream in the presence of a dissolved or dispersed catalyst, distilling the product stream to separate an overhead stream (2) from a catalyst-containing bottoms stream, distilling stream (2) to obtain an overhead stream enriched in (Z)-2-methyl-2-butenonitrile and a bottoms stream (5), and distilling stream (5) to produce a bottoms stream containing 3-pentenonitrile and an overhead stream containing 2-methyl-3-butenonitrile.

Abstract: A process for removing a compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group and carboxamide group, from a mixture which comprises a compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group and carboxamide group, and a compound which is homogeneous with respect to the mixture and contains rhodium, by distillation.

Abstract: A process for hydrogenating a monoolefinically unsaturated compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group, carboxamide group to a saturated compound which bears the same at least two functional groups, in the presence of a rhodium-containing compound, as a catalyst, which is homogeneous with respect to the reaction mixture.

Abstract: The invention relates to a method for reducing the content of an aliphatic, monounsaturated amine (III) in a mixture (IV) containing an aminonitrile (I) or a diamine (II), or mixtures thereof and an amine (III). Said method is characterised in that a) mixture (IV) is reacted with an anionic nucleophile (V) in a quantity ranging between 0.01 and 10 mol per mol of amine (III) in mixture (IV) to obtain a mixture (VI). The invention is also characterised in that b) aminonitrile (I) or diamine (II) or mixtures thereof are removed by distillation from mixture (VI), at a temperature ranging between 50 and 170 DEG C and a pressure of between 0.5 and 100 kPa.
