Abstract
A process for the simultaneous production of fructose and of gluconic acid from glucose-fructose mixtures and/or from invert sugar by the selective oxidation of the glucose proportion, wherein oxygen and/or air, activated by noble metal catalysts, are utilized as the oxidizing agents; the oxidation is conducted in a pH range of about 8 to 10; and the oxidation is terminated after the formation of 1 equivalent of carboxylic acid per mole of glucose employed. The thus-obtained gluconic acid can subsequently be separated from the unchanged fructose in a simple way and practically quantitatively, and can be isolated as the salt.
