摘要：
Claim 1: A process for preparing N- (phosphonomethyl) glycine comprising the oxidation of N- (phosphonomethyl) iminodiacetic acid or a salt thereof, characterized in that said process comprises: contacting N- (phosphonomethyl) iminodiacetic acid with an agent oxidant in an aqueous reaction medium within an oxidation reaction zone in the presence of an oxidation catalyst, to thereby effect the oxidation of N- (phosphonomethyl) iminodiacetic acid and produce a reaction solution comprising N- (phosphonomethyl) ) glycine or other intermediate that can be converted to N- (phosphonomethyl) glycine；and continue treating said reaction solution to obtain an N- (phosphonomethyl) glycine product that does not contain more than about 600 ppm of N- (phosphonomethyl) iminodiacetic acid or a salt thereof； wherein the oxidation of N- (phosphonomethyl) iminodiacetic acid in said aqueous reaction medium is continued until the concentration of N- (phosphonomethyl) iminodiacetic acid in said reaction medium has been reduced to a terminal concentration such that said additional treatment yields an N- (phosphonomethyl) glycine product with an N- (phosphonomethyl) iminodiacetic acid content not greater than about 600 ppm by weight, based on the N- (phosphonomethyl) glycine.Reivindicación 1: Un proceso para preparar N-(fosfonometil)glicina que comprende la oxidación de ácido N-(fosfonometil)iminodiacético o una sal del mismo, caracterizado porque dicho proceso comprende: poner en contacto ácido N-(fosfonometil)iminodiacético con un agente oxidante en un medio de reacción acuoso dentro de una zona de reacción de oxidación en presencia de un catalizador de oxidación, para efectuar de esa manera la oxidación de ácido N-(fosfonometil)iminodiacético y producir una solución de reacción que comprende N-(fosfonometil)glicina u otro intermediario que se puede convertir a N-(fosfonometil)glicina； y seguir tratando dicha solución de reacción para obtener un producto N-(fosfonometil)glicina que no con
