Abstract
Un procedimiento de producción de adiponitrilo, comprendiendo dicho procedimiento las etapas de: (a) hacer reaccionar en una primera zona de reacción una mezcla que comprende 1,3 - butadieno (BD) y cianuro de hidrógeno (HCN) en presencia de un primer catalizador que comprende Ni de valencia cero y un primer ligando que contiene fósforo para producir un producto de reacción que comprende 3 - pentenonitrilo (3PN) y 2 - metil - 3 - butenonitrilo (2M3BN); (b) isomerizar al menos una parte del 2M3BN de la etapa (a) en una segunda zona de reacción en presencia de un segundo catalizador que comprende Ni de valencia cero y un segundo ligando que contiene fósforo para producir un producto de reacción que comprende 3PN; y (c) hacer reaccionar en una tercera zona de reacción una mezcla que comprende 3PN de la etapa (b) y cianuro de hidrógeno (HCN) en presencia de un tercer catalizador que comprende Ni de valencia cero y un tercer ligando que contiene fósforo y en presencia de un promotor de ácido Lewis para producir un producto de reacción que comprende adiponitrilo, en el que el catalizador fluye a través de la primera, la segunda y la tercera zona de reacción junto a reactivos y productos, en el que el producto de la reacción de la etapa (a) comprende, además, dinitrilos que comprenden adiponitrilo (ADN) y metilglutaronitrilo (MGN), en el que, al menos, una parte del catalizador que fluye a través de la primera zona de reacción se recicla en la primera zona de reacción, y en el que el catalizador que fluye a través de la tercera zona de reacción se recicla en la tercera zona de reacción, en el que una parte de la corriente de reciclado del catalizador se pone en contacto con un primer disolvente de extracción en una primera etapa de extracción de líquido / líquido para producir una fase de disolvente y una fase de refinado, en el que se emplea una etapa de extracción de líquido / líquido separada para tratar el producto de la tercera zona de reacción de manera que dicho tercer catalizador no esté en contacto con dicho disolvente de extracción en dicha primera etapa de extracción de líquido / líquido, en el que la primera etapa de extracción de líquido / líquido comprende la introducción de una parte de la corriente de reciclado del catalizador, una primera corriente de disolvente de extracción y una corriente de reciclado de dinitrilo que comprende adiponitrilo (ADN) en una primera zona de extracción de líquido / líquido, en el que la primera etapa de extracción de líquido / líquido comprende además la separación de los líquidos en la primera zona de extracción de líquido / líquido en una primera fase de disolvente que comprende un primer disolvente de extracción y el catalizador y una primera fase de refinado que comprende adiponitrilo (ADN), metilglutaronitrilo (MGN), compuestos con un punto de ebullición mayor que el adiponitrilo (ADN) y compuestos con un punto de ebullición menor que el metilglutaronitrilo (MGN); en el que el catalizador de dicha primera fase de disolvente obtenido se recicla en la primera etapa de extracción de líquido / líquido en la primera, la segunda o ambas zonas de reacción, en el que dicha primera fase de refinado se destila en una o más etapas de destilación para separar adiponitrilo (ADN) y metilglutaronitrilo (MGN) de compuestos con un punto de ebullición mayor que el adiponitrilo (ADN) y compuestos con un punto de ebullición menor que el metilglutaronitrilo (MGN) para obtener una primera corriente de dinitrilo refinado, en el que dicha primera corriente de dinitrilo refinado se destila adicionalmente para retirar metilglutaronitrilo (MGN) de la primera corriente de dinitrilo refinado para obtener una segunda corriente de dinitrilo refinada rica en adiponitrilo, y en el que al menos una parte de dicha segunda corriente de dinitrilo refinado se recicla en la primera etapa de extracción de líquido / líquido.
