| titleOfInvention | Method for producing cyclic lactams |
| abstract | The invention relates to a method for producing cyclic lactams of formula (I), in which R1 stands for a hydrogen atom, an alkyl, a cycloalkyl or an aryl; A stands for a C3-C12-alkylene radical, which can be substituted by 1, 2, 3, 4, 5 or 6 substituents, selected independently from each other from the alkyl, cycloalkyl or aryl groups. In this method, a .omega.-amino carbonic acid nitrile of formula (II) HR1N - A - CN, in which R1 and A have the meaning given above, is reacted in the presence of at least one catalyst. The method is characterized in that nitrile II is converted into an oligomer mixture and then treated with overheated water vapour. |
