Abstract

PROCESO PARA LA ELABORACION DE POLIAMIDAS CON CAPACIDAD DE HILADO A PARTIR DE {AL''}, {OE} - DINITRILOS ALQUIL Y {AL''} , {OE} - DIAMINAS ALQUIL ASI COMO AGUA EN EXCESO, DONDE A) LA SOLUCION ACUOSA DEL DINITRILO SE TRANSFORMA EN PRESENCIA DE DIAMINA CON UNA CANTIDAD ACTIVA CATALITICA AL MENOS DE UN ACIDO DE FOSFORO QUE CONTIENE OXIGENO Y/O UNA SAL SOLUBLE EN AGUA DE CALCIO, ZINC, MANGANESO O CADMIO. EL VALOR PH DE ESTA DISOLUCION SE AJUSTA SOBRE UN VALOR DE PARTIDA EN LA ZONA DESDE 2,0 HASTA 4,0 MEDIANTE ADICION DE UN ACIDO CARBOXILICO ALIFATICO SATURADO O AROMATICO Y EL DINITRILO SE HIDROLIZA EN TEMPERATURA ELEVADA Y PRESION AUTOGENA PARA LA OBTENCION DE ACIDO DICARBOXILICO, Y B) LA SOLUCION A PARTIR DE LA ETAPA A) SE ADICIONA AL MENOS CON DIAMINA EN CANTIDAD EQUIMOLAR Y LA MEZCLA SE POLICONDENSA PARA LA OBTENCION DE POLIAMIDA.
