Abstract

Un procedimiento mejorado para la recuperación y purificación de acrilonitrilo o metacrilonitrilo producido por la reacción de oxidación amoniacal de propileno o isobutileno, oxígeno molecular y amoníaco en presencia de catalizadores de oxidación amoniacal, que comprende: a) poner en contacto el efluente del reactor de oxidación amoniacal que contiene acrilonitrilo o metacrilonitrilo, acetonitrilo, e impurezas con un líquido acuoso de enfriamiento brusco en un sistema de enfriamiento brusco para producir un efluente gaseoso de enfriamiento brusco procedente de dicho sistema de enfriamiento brusco; b) absorber dicho efluente de enfriamiento brusco en agua para formar una solución acuosa; c) alimentar la solución acuosa a un plato intermedio de una columna de destilación que tiene una pluralidad de platos, utilizando agua como disolvente introducida en el extremo superior de dicha columna para realizar una destilación extractiva del agua, donde una corriente de vapores de cabezas de acrilonitrilo o metacrilonitrilo con algo de agua se separa por el extremo superior de la columna, y una corriente líquida que contiene agua e impurezas se separa por el fondo de la columna; d) separar una primera corriente lateral procedente de la mitad inferior de dicha columna para recuperar el acetonitrilo; e) alimentar al menos una parte de las colas líquidas procedentes de dicha columna al sistema de enfriamiento brusco como líquido de enfriamiento brusco, caracterizado porque se prepara una corriente de vapores que contiene agua procedente de la cuarta parte inferior de dicha columna.
