Abstract

PROCEDIMIENTO PARA GENERAR EL DISOLVENTE DE EXTRACCION DE ACIDO FOSFORICO. SE TRATA, PARTICULARMENTE, DE LAVAR UN DISOLVENTE SUSTANCIALMENTE INMISCUIBLE EN AGUA CON UNA SOLUCION ACUOSA, PARA SEPARAR IMPUREZAS DEL DISOLVENTE, ELIGIENDOSE ESTE ENTRE ALQUILFOSFATOS, ARILFOSFATOS Y ALQUILARILFOSFATOS, E INCLUYENDO TAMBIEN OPCIONALMENTE UN DILUYENTE ORGANICO INMISCIBLE. EL DISOLVENTE HA SIDO UTILIZADO PARA EXTRACTAR ACIDO FOSFORICO DE UNA SOLUCION IMPURA DE ACIDO FOSFORICO Y DE LA CUAL SE HA SEPARADO EL ACIDO FOSFORICO. EL LAVADO DEL DISOLVENTE SE REALIZA CON UNA SOLUCION ACUOSA QUE CONTIENE SUFICIENTE CANTIDAD DE ORTOFOSFATO DE METAL ALCALINO PARA MANTENER EL PH DE LA MEZCLA DISOLVENNTE/FASE ACUOSA EN 9,5-12,5.
