ABSTRACT:
A salt of pyruvic acid is formed by oxidizing a salt of lactic acid with an oxygen-containing gas in a water-containing solvent in the presence of a catalyst. The catalyst used herein comprises (a) at least one component selected from platinum and palladium and (b) at least one component selected from lead, tin, tellurium, indium, bismuth, and compounds of these elements. The resulting pyruvate is isolated in the form of a solid by concentrating the catalyst-free reaction mixture and then mixing isopropyl alcohol therewith.
