Abstract

Se describe un procedimiento para purificar soluciones de Glifosato (N-fosfonometilglicina) provenientes de la síntesis del Glifosato mediante la oxidación del ácido N-fosfonometilimidodiacético, y que contienen formaldehído y ácido fórmico como impurezas principales, caracterizado porque comprende: proveer una solución inicial de Glifosato ajustar en pH de dicha solución inicial de Glifosato someter dicha solución a una operación de nanofiltración, realizando la misma mediante, al menos, una membrana de nanofiltración recuperar la solución concentrada de Glifosato y descartar la solución permeada que contiene entre el 50 y el 95% del formaldehído y del ácido fórmico presentes en dicha solución inicial.A process for purifying glyphosate (N-phosphonomethylglycine) solutions from the synthesis of glyphosate by the oxidation of N-phosphonomethylimidodiacetic acid, and containing formaldehyde and formic acid as main impurities, characterized in that it comprises: providing an initial solution of glyphosate is described. adjust the pH of said initial glyphosate solution to subject said solution to a nanofiltration operation, performing the same by at least one nanofiltration membrane recovering the concentrated glyphosate solution and discarding the permeate solution containing between 50 and 95% of formaldehyde and formic acid present in said initial solution.
