Participants

Reaction Steps

The process of the present invention involves contacting N-phosphonomethyliminodiacetic acid in a slurry or solution with a water soluble salt or a salt complex of selected metals in the presence of a quinone or hydroquinone. The mixture or solution is contacted with a peroxide while heating the reaction mass to a temperature sufficiently high to initiate and sustain the oxidation reaction of N-phosphonomethyliminodiacetic acid to produce N-phosphonomethylglycine.
