    Abstract: A process for reducing the level of an aliphatic monounsaturated amine (IV) in a mixture (V) containing an aminonitrile (I) or a diamine (II) or a dinitrile (III) or mixtures thereof as well as said mine (IV) by a) reacting said mixture (V) with an anionic nucleophile (VI) which contains a nucleophilic atom selected from the group consisting of oxygen, nitrogen and sulfur, which is capable of taking up an H + ion to form an acid having a pK a value in the range from 7 to 11, as measured in water at 25° C., and which has a relative nucleophilicity, as measured in methyl perchlorate/methanol at 25° C., in the range from 3.4 to 4.7 when said nucleophilic atom is oxygen, in the range from 4.5 to 5.8 when said nucleophilic atom is nitrogen, and in the range from 5.5 to 6.8 when said nucleophilic atom is sulfur, in an amount in the range from 0.01 to 10 mol per mole of said amine (IV) in said mixture (V) at a temperature in the range from 50 to 200° C. to obtain a mixture (VII), b) distilling said aminonitrile (I) or said diamine (II) or said dinitrile (III) or mixtures thereof from said mixture (VII) at a temperature in the range from 50 to 200° C. and at a pressure in the range from 0.1 to 100 kPa to obtain a bottom product (VIII), which comprises c) distilling an aminonitrile (I) or diamine (II) or dinitrile (III) or mixtures thereof from said bottom product (VIII) at a temperature which is lower than that chosen in step b).

    Abstract: The invention relates to a method for producing cyclic lactams of formula (II) 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 R and R represent C1-C6 alkyl, C5-C7 cycloalkyl or C6-C12 aryl groups. In formula (I), R , R , 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: The invention relates to a method for producing cyclic lactams of the formula (II), wherein n and m may each represent 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, R and R represent C1-C6 alkyl, C5-C7 cycloalkyl or C6-C12 aryl groups, by reacting a compound of the formula (I), wherein R , R , m and n have the meaning indicated above, and R represents nitrile groups, carboxylic acid amide groups and carboxylic acid groups, with water vapor in the gaseous phase. The inventive method is further characterized in that a) the compound (I) is reacted with water vapor in the gaseous phase, adding an organic diluent (III) before or after the reaction, which diluent has a miscibility gap under certain quantitative, pressure and temperature conditions, said reaction resulting in a mixture (IV) that contains a lactam (II), b) adjusting the mixture (IV) before or after the removal of ammonia to quantitative, pressure and temperature conditions under which the diluent (III) and water are present in a liquid form and have a miscibility gap, and obtaining a two-phase system consisting of a phase (V) that has a higher proportion of diluent (III) than water, and a phase (VI) that has a higher proportion of water than diluent (III), c) separating phase (V) from phase (VI) and, d) removing from phase (V) the diluent (III) and optionally by-products selected from the group of the low-boilers, high-boilers and unreacted compound (I), and obtaining a lactam (II).
