Abstract
Un proceso de preparación de poliamidas en donde se somete a una reacción una mezcla que comprende hexametilendiamina y aminocapronitrilo obtenida de la hidrogenación de adiponitrilo con agua y un ácido dicarboxílico. La mezcla de hidrogenación utilizada puede derivar directamente de la etapa de hidrogenación no ha sido sometida a proceso de purificación alguno. El ácido dicarboxílico utilizado puede ser ácido adípico o ácido tereftálico y la cantidad de ácido dicarboxílico puede oscilar entre 50 y 150 mol %, con respecto a la cantidad de hexametilendiamina en la mezcla. El agua se puede utilizar bajo una relación molar que oscila entre 1:1 y 6:1 con relación al aminocapronitrilo. El proceso puede comprender los pasos de: 1) mezcla de la mezcla de hidrogenación de hexametildiamina y aminocapronitrilo con agua y un ácido dicarboxílico para formar una mezcla de reacción y subsecuente conversión a una temperatura que oscila entre 90 y 300° C y bajo una presión a la cual dicha mezcla de reacción constituye una única fase líquida; 2) conversión adicional de la mezcla de conversión del paso 1) a una temperatura que oscila entre 230 y 400° C y bajo una presión a la cual se obtienen una fase líquida y una fase gaseosa, separación de la fase gaseosa de la fase líquida; y 3) poscondensación de la mezcla de producto a una temperatura que oscila entre 250 y 310° C y bajo una presión que es inferior a aquélla del paso 2). La conversión se puede llevar a cabo en presencia de un catalizador de lecho fijo con óxido metálico en uno o más pasos y el catalizador puede ser seleccionado entre una beta-zeolita, silicato en láminas, óxido de aluminio o dióxido de titanio. Una poliamida que puede ser preparada mediante el proceso descripto.
