Abstract
This process for the production of 2-keto-D-gluconic acid starts from D-glucose. D-glucose is catalytically oxidised using molecular oxygen in a one-pot process. The oxidation is performed in the presence of well-known Pt/Pb catalysts. The initial reaction to D-gluconic acid is performed at constant pH between 7 and 10. There after the reaction is continued without pH control. This process results in a high selectivity compared with known processes.
