Abstract

PROCEDIMIENTO PARA LA OBTENCION DE FLOCULANTES POLIMEROS CATIONICOS DEL TIPO DE ACRILAMIDA, QUE CONTIENEN ACRILAMIDA POLIMERIZANTE, OBTENIDA POR HIDRATACION CATALITICA DE ACRILONITRILO CON AGUA. CONSISTE EN HACER SUSTANCIALMENTE LIBRE DE N-ACRILOIL ACRILAMIDA UNA DISOLUCION ACUOSA CRUDA DE ACRILAMIDA, OBTENIDA POR LA HIDRATACION CATALITICA, MEDIANTE ADSORCION FISICA, ADSORCION REACTIVA, DESCOMPOSICION POR UNA REACCION QUIMICA Y ESTRACCION; SEGUIDO DE LA POLIMERIZACION DE LA ACRILAMIDA CONTENIDA EN LA DISOLUCION HASTA OBTENER UN FLOCULANTE CATIONICO DE ALTO PESO MOLECULAR.PROCEDURE FOR OBTAINING CATIONIC POLYMER FLOCULANTS OF THE TYPE OF ACRYLAMIDE, CONTAINING ACRYLAMIDE POLYMERIZING, OBTAINED BY CATALYTIC HYDRATION OF ACRYLONITRILE WITH WATER. IT CONSISTS OF MAKING A CRUDE AQUEOUS ACRYLAMIDE SOLUTION, OBTAINED BY CATALYTIC HYDRATION, BY PHYSICAL ADSORTION, REACTIVE ADSORTION, DECOMPOSITION BY A CHEMICAL REACTION; FOLLOWED BY THE POLYMERIZATION OF THE ACRYLAMIDE CONTAINED IN THE SOLUTION UNTIL A HIGH MOLECULAR WEIGHT CATIONIC FLOCULANT IS OBTAINED.
