Abstract
Un procedimiento de purificacion de lactamas, más particularmente de lactamas obtenidas por hidrolisis ciclizante de aminonitrilo. Purificacion de e-caprolactama obtenida por hidrolisis ciclizante de aminocapronitrilo, que consiste en la remocion de amoníaco del medio de reaccion de hidrolisis y en la recuperacion de lactama de dicho medio en forma purificada. Esta recuperacion se lleva a cabo empleando al menos una destilacion de la lactama en presencia de una base, opcionalmente produciendo una fraccion superior que comprende compuestos que son más volátiles que la lactama, una fraccion que comprende la lactama para ser recuperada con el grado deseado de pureza y un producto de destilacion del fondo que comprende lactama y compuestos que son menos volátiles que la lactama. El producto de destilacion del fondo es tratado mediante varios procesos, tales como evaporacion en capa fina, de manera tal de recuperar la mayoría de la caprolactama presente, y reciclar esta ultima en el proceso de purificacion. Es posible un alto grado de recuperacion de la caprolactama presente en el medio de hidrolisis, mientras se observa el criterio de pureza requerido.
