Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ACIDO N,N-DI(ACIDO ACETICO)-AMINOMETILENFOSFONICO. COMPRENDE LA HIDROLISIS DE IMINODIACETONITRILO CON UNA BASE DE METAL ALCALINO; SEGUIDA POR EL TRATAMIENTO DE LA SAL DIALCALINA FORMADO CON UNA DISOLUCION ACUOSA DE UN ACIDO FUERTE, COMO ACIDO CLORHIDRICO; REACCION CON ACIDO FOSFOROSO Y FORMALDEHIDO EN DISOLUCION ACUOSA DE ACIDO CLORHIDRICO, FORMADA POR ADICION DE TRICLORURO DE FOSFORO AL MEDIO DE REACCION; DISOLUCIN DEL CLORURO DE METAL ALCALINO POR DILUCION CON AGUA, Y SEPARACION DEL ACIDO FOSFONICO DESEADO. ESTE COMPUESTO TIENE APLICACIONES COMO INTERMEDIO PARA LA SINTESIS DEL HERBICIDA N-FOSFONOMETILGLICINA (GLIFOSFATO).
