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 i n 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 ~C and a pressure of between 0.5 and 100 kPa.

Abstract: The invention relates to a method for producing cyclic lactams of formula (I I) by reacting a compound (I) of formula (I) with water in the presence of an organic, liquid dilution agent in the liquid phase. In formula (II), n and m respectively can have the values 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 and the sum of n + m is at least 3, preferably at least 4 and R1 and R2 represent C1-C6 alkyl, C5-C7 cycloalkyl or C6-C12 aryl groups. In formula (I), R1, R2, m and n are defined as above and R represents nitrile, carboxylic acid amide and carboxylic acid groups. The inventive method is characterized in that a) compound (I) is reacted with water in the liquid phase in the presence of an organic, liquid dilution agent (III) to form a mixture (IV) containing a lactam (II) and said mixture (IV) is subjected to an aqueous treatment to obtain a two-phase system.

Abstract: A process for extractively removing homogeneously dissolved catalysts from a reaction effluent of a hydrocyanation of unsaturated mononitriles to dinitriles with a hydrocarbon H, including performing the steps of a) concentrating the reaction effluent before step b) by distillation at pressures of from 0.1 to 5000 mbar and temperatures of from 10 to 150° C., b) adding a hydrocarbon H to the concentrated reaction effluent to obtain a stream I, and c) feeding stream I, without prior separation of the liquid phases, into an extraction apparatus and extracting it at a temperature T with the hydrocarbon H to obtain a stream II comprising the hydrocarbon H enriched with the catalyst and a stream III having a low catalyst content.
