ABSTRACT:
The invention provides a process for the production of N-(phosphonomethyl)glycine, also known as glyphosate. The process comprises hydrogenating a mixture containing glyoxylic acid and aminomethylphosphonic acid, the mixture having been enzymatically prepared in situ by the reaction of glycolic acid and oxygen in an aqueous solution containing aminomethylphosphonic acid and the enzymes glycolate oxidase and catalase.
