METHOD FOR SELECTIVE CARBOHYDRATE OXIDATION USING SUPPORTED GOLD CATALYSTS

摘要

Disclosed is a method for the selective oxidation of at least one oligosaccharide, a mixture thereof or a composition having a content thereof, where an aqueous solution of the oligosaccharide, of the mixture or of the composition is reacted in the presence of a gold catalyst comprising nanodispersed gold particles on a carbon support, and of oxygen, where an aldehyde group on the C1 carbon atom of the oligosaccharide(s) is selectively oxidized to a carboxyl group, or an aldehyde group is introduced on the C1 carbon atom and selectively oxidized to a carboxyl group.
