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.

Claims

2. A method, as claimed in claim 1, wherein the compound is a monosaccharide.

3. A method, as claimed in claim 2, wherein the monosaccharide is glucose.

4. A method, as claimed in claim 1, wherein the catalyst is selected from the group consisting of copper glycinate, copper acetylacetonate, copper phthalocyanine disulfonate, copper phthalocyanine, copper glutamate and copper diethylene tetramine pentaacetate.

5. A method, as claimed in claim 4, wherein the catalyst is copper glycinate.

6. A method, as claimed in claim 1, wherein the amount of catalyst is equal to from about 2% to about 7% by weight based on the weight of the compound employed.

7. A method, as claimed in claim 6, wherein the amount of catalyst is equal to from about 3% to about 6% by weight based on the weight of the compound employed.

8. A method, as claimed in claim 1, wherein an oxygen-containing gas is employed.

9. A method, as claimed in claim 8, wherein the oxygen-containing gas is air.
