A process for producing aldehydes, and/or carboxylic acids is described, in which a primary alcohol, especially a carbohydrate, is oxidized using a catalytic amount of a nitrosonium compound obtained by oxidizing a nitroxyl compound in the presence of an enzyme compound capable of oxidation. Further described are oxidized carbohydrates containing at least 1 cyclic monosaccharide chain group carrying a carbaldehyde group per 25 monosaccharide units and per molecule.

Process for selective oxidation of primary alcohols and novel carbohydrate aldehydes

A process for oxidizing cellulose, in which a nitroxyl compound such as TEMPO is oxidized using an oxidizing agent in the presence of a complex of a transition metal such as Mn, Fe, Cu, and a complexing agent such as a polyamine, or an oxidative enzyme, and the resulting nitrosonium ion is used to selectively oxidize cellulose 6-hydroxy-methylene groups to carbaldehyde groups and carboxylic acid groups.
