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.
