Abstract

PROCEDIMIENTO DE PREPARACION DE N-FOSFONOMETILGLICINA, SEGUN EL CUAL SE OXIDA EL ACIDO N-FOSOFNOMETILIMINODIACETICO EN UN MEDIO ACIDO FULFURICO ACUOSO CON PEROXIDO DE HIDROGENO. UNA CARACTERISTICA ES EL USO COMO MEDIO DE REACCION DE AGUAS ACIDAS RESIDUALES FORMADAS COMO ACIDO SULFURICO ACUOSO Y OBTENIDAS DESPUES DE LA SEPARACION DE LA N-FOSFONOMETILGLICINA AL REALIZAR LA OXIDACION. SE DILUYE ESTA DISOLUCION FACULTATIVAMENTE CON AGUA HASTA UNA CONCENTRACION DE 12-18% EN PESO DE ACIDO SULFURICO Y 3-% EN PESO DE N-FOSFONOMETILGRLICINA.
