Beschreibung
Zusammenfassung:	The invention pertains to a method for oxidizing a carbohydrate into a dialdehyde carbohydrate using periodic acid, and regenerating the periodic acid used in the carbohydrate oxidation, involving first oxidizing a carbohydrate using periodic acid, to obtain the corresponding dialdehyde carbohydrate and iodic acid, wherein the iodic acid thus generated is subjected to a two-step electrolytic process, wherein the iodic acid is first electrolytically regenerated into periodate under alkaline conditions, and the periodate thus formed is then electrolytically acidified to periodic acid, which periodic acid is returned to the carbohydrate oxidation.
