An oxidation catalyst is prepared by pyrolyzing a source of iron and a source of nitrogen on a carbon support. Preferably, a noble metal is deposited over the modified support which comprises iron and nitrogen bound to the carbon support. The catalyst is effective for oxidation reactions such as the oxidative cleavage of tertiary amines to produce secondary amines, especially the oxidation of N-(phosphonomethyl)iminodiacetic acid to N-(phosphonomethyl)- glycine.
Un catalyseur d'oxydation est préparé par pyrolyse d'une source de fer et d'une source d'azote sur un support de carbone. De préférence, un métal noble est déposé sur le support modifié lequel comprend du fer et de l'azote liés au support de carbone. Le catalyseur est efficace pour des réactions d'oxydation telles que le clivage oxydatif d'amines tertiaires pour produire des amines secondaires, notamment l'oxydation d'acide N-(phosphonométhyl)iminodiacétique en N-(phosphonométhyl)-glycine.
