    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.

    Abstract: La presente invencion se refiere a la caprolactama que se prepara haciendo reaccionar una solucion de 6-aminocapronitrilo con agua en la fase líquida a temperaturas elavadas mediante un proceso en el cual, (a) una solucion de 6-aminocapronitrilo en fase líquida se calienta sin la adicion de un catalizador en un reactor A para dar una mezcla I que cosiste esencialmente en agua, caprolactama y una fraccion de elevado punto de ebullicion (ebullidor elevado), luego (b) el agua se retira de la mezcla resultante I para dar una mezcla II que consiste esencialmente en caprolactama y los ebullidores elevados, después (c) la caprolactama y los ebullidores elevados de la mezcla II se separan por destilacion, y luego (D1) los ebullidores elevados de la etapa (c) se alimentan al reactor A de la etapa (a), o (d2) los ebullidores elevados se calientan de la misma manera que en la etapa (a) en otro reactor B y luego se procesan de la misma manera que etapas (b) y (c) para producir más caprolactama, o (d3) los ebullidores elevados se calientan a presion reducida en presencia de una base en un reactor C y la mezcla que reacciono se trabaja por destilacion para dar caprolactama.
