    • The invention relates to a method for the oxidation of a secondary hydroxy group of an organic compound to a keto group in the presence of at least one primary hydroxy group of said organic compound, especially for producing dihydroxyacetone (DHA) from glycerin. According to said method, the organic compound, particularly the glycerin, is reacted with oxygen in the presence of a supported metal catalyst, especially a multi-metal catalyst, comprising gold and platinum and other optional metals catalyzing oxidation of said organic compound, particularly glycerin, in an alkaline aqueous system so as to form an organic compound containing a keto group and at least one primary hydroxy group, especially of dihydroxyacetone. Preferably, the supported oxidation catalysts used in said method are obtained by carrying out the following steps: a) at least one metal salt and/or at least one acid of a metal which can catalytically oxidize hydroxyl groups to aldehyde groups or keto groups is reduced using at least one reducing stabilizer according to the Sol method in an alkaline aqueous system; b) a supporting material is contacted with the alkaline aqueous system and supports of the supporting material; c) the solid moiety is separated from the liquid portion; d) the separated solid moiety is washed; and e) the washed solid moiety is tempered. The invention further relates to the supported oxidation catalysts obtained according to the disclosed method.
