Abstract
Procedimiento para la separación de componentes de alto punto de ebullición de una caprolactama cruda, que contiene componentes de alto punto de ebullición, caprolactama, opcionalmente. Componentes de bajo punto de ebullición, y que se ha obtenido por a) reacción de 6-aminocapronitrilo con agua dando una mezcla de reacción, b) separación de amoníaco y del agua no reaccionada de la mezcla de reacción, obteniéndose una caprolactama cruda, cuyo procedimiento está caracterizado porque c) se introduce la caprolactama cruda en un dispositivo de destilación, obteniéndose una primera corriente parcial por la cabeza como producto y una segunda corriente parcial por el fondo, ajustándose en la destilación una presión tal, que la temperatura en el fondo no pase por debajo de 170sC, y ajustándose la segunda corriente parcial de tal manera, que el contenido en caprolactama de la segunda corriente parcial no sea más baja que un 10% en peso, con respecto a toda la corriente parcial.
