Abstract

Un proceso para la purificacion de lactamas en particular las lactamas obtenidas por hidrolisis ciclizante de un aminoalquilonitrilo. Más particularmenteepsilon-caprolactama obtenida por hidrolisis ciclizante de aminocapronitrilo. Esta cristalizacion puede llevarse a cabo tanto directamente sobre el medio dereaccion de la ciclizacion luego de la remocion de los compuestos volátiles, como sobre un medio que ha sufrido varios tratamientos o sobre una carprolactamaextraída del medio de reaccion, po r ejemplo mediante destilacion.
