Abstract

Un proceso por medio del cual se fabrica N-fosfonometilglicina (glifosato) o sus sales mediante:1) la formación de N-fosfonometilglicinonitrilo mediante la reacción de ácido aminofosfónico, un cianuro de metal álcali y formaldehido en una soluciónacuosa a un pH en el margen de 10 a 13 (y preferiblemente de 11 a 11,5) mientras que se le agrega ácido mineral a una tasa suficiente como paramantener el pH dentro del margen deseado, y a continuación 2) la hidrolizacióndel N-fosfonometilglicinonitrilo producto de la Etapa (1)para formar una sal de N-fosfonometilglicina y opcionalmente 3) la neutralización de la sal de N-fosfonometilglicina para formarN-fosfonometilglicina.
