ABSTRACT:
The invention provides a process for producing mixtures of glyoxylic acid and aminomethylphosphonic acid. The process comprises reacting glycolic acid and oxygen in an aqueous solution in the presence of aminomethylphosphonic acid catalyst consisting of glycolate oxidase and catalase. The resulting mixtures are useful intermediates in the production of N-(phosphonomethyl)glycine.
