The oxidation of sugars. I. The electrolytic oxidation of aldose sugars in the presence of a bromide and calcium carbonate

Abstract

A new method has been devised for the preparation of calcium salts of the sugar acids in which the sugar is electrolytically oxidized in the presence of- calcium carbonate and a bromide. The sugar is oxidized in manner analogous to the well-known bromine oxidation, but since only a small quantity of bromide is used as a catalyst, the new method has the decided advantage that the reaction product does not contain any objectionable substances derived from the oxidant.
