Abstract

Abstract A compound selected from the group consisting of monosaccharides containing at least 4 carbon atoms, polyhydric alcohol derivatives of these monosaccharides, and polyhydric acid derivatives of these monosaccharides is oxidized by contacting an aqueous solution of the compound, in the presence of an alkaline material and a catalyst selected from the group consisting of copper glycinate, copper acetylacetonate, copper phthalocyanine disulfonate, copper phthalocyanine, copper glutamate, copper diethylene tetramine pentaacetate, cobalt glutamate, cobalt acetylacetonate, cobalt trisodium diethylene tetramine pentaacetate, and cobalt disodium ethylene diamine tetraacetate, with oxygen or an oxygen-containing gas.
