Abstract
Procedimiento continuo para la obtención de una poliamida mediante reacción de al menos un aminonitrilo con agua, que comprende las siguientes etapas: (1) reacción de al menos un aminonitrilo con agua en proporción molar 1 : 1 a 1 : 10, a una temperatura de 90 a 400ºC y una presión de 0,1 a 15 x 106 Pa en un tubo de circulación, que contiene cuerpos de relleno de un catalizador ácido de Brönsted, seleccionados a partir de cuerpos de relleno de beta-zeolita, silicato laminar o dióxido de titanio, y cuerpos de relleno metálicos, estando apilados alternantemente en el tubo de circulación los cuerpos de relleno de un catalizador ácido de Brönsted, seleccionados a partir de cuerpos de relleno de beta-zeolita, silicato laminar o dióxido de titanio, y los cuerpos de relleno metálicos, obteniéndose una mezcla de reacción, (2) reacción adicional de la mezcla de reacción a una temperatura de 150 a 400ºC y una presión que es menor que la presión en la etapa 1, seleccionándose la temperatura y la presión de manera que se obtiene una primera fase gaseosa y una primera fase líquida o una primera fase sólida, o una mezcla constituida por la primera fase sólida y la primera fase líquida, y separándose la primera fase gaseosa de la primera fase líquida o la primera fase sólida, o de la mezcla constituida por la primera fase líquida y la primera fase sólida, y (3) mezclado de la primera fase líquida o la primera fase sólida, o de la mezcla constituida por la primera fase líquida y la primera fase sólida, con una fase gaseosa o líquida que contiene agua, a una temperatura de 150 a 370ºC, y una presión de 0,1 a 30 x 106 Pa, obteniéndose una mezcla de productos.
