| titleOfInvention | Process for the preparation of cyclic lactams |
| abstract | "PROCESS FOR PREPARING CYCLIC LACTAMS". 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 a liquid organic diluting agent in the liquid phase. In formula (II), neither may respectively 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, R4. R1 and R2 represent C1 -C6 alkyl, C5 -C7 cycloalkyl or C6 -C12 aryl groups. In formula (I), R 1, R 2, R 2, m and n are as defined above and R represents nitrile, carboxylic acid amide and carboxylic acid groups. The method of the invention is further characterized in that a) compound (1) is reacted with water in the liquid phase in the presence of a liquid organic diluting agent (III) to form a mixture (IV) containing a lactam (II) and said mixture (IV) is subjected to an aqueous treatment to obtain a dual phase system. |
