Abstract
A process for the production of glyoxylic acid by reacting glycolic acid and oxygen in an aqueous solution at pH 7-10 in the presence of the enzyme glycolate oxidase and a non-enzymatic catalyst for the decomposition of hydrogen peroxide, and an amine buffer capable of forming a chemical adduct with glyoxylic acid.
