Title (EN) PRODUCTION OF GLYOXYLIC ACID BY ENZYMATIC OXIDATION OF GLYCOLIC ACID
(FR) PRODUCTION D'ACIDE GLYOXYLIQUE PAR OXYDATION ENZYMATIQUE D'ACIDE GLYCOLIQUE
Abstract:
(EN) Improved process for the production of glyoxylic acid by the glycolate catalyzed oxidation of glycolic acid, providing a commercially practical method for the production of glyoxylic acid through the increase of starting substrate concentrations and through the selective use of yield improving additives.
(FR) Procédé amélioré de production d'acide glyoxylique par oxydation catalysée par glycolate d'acide glycolique, constituant un procédé commercialement pratique de production d'acide glyoxylique par l'augmentation des concentrations de substrats de départ, et par l'emploi sélectif d'additifs améliorant le rendement.
