A novel process for producing pyruvic acid is provided in which process hydroxyacetone is oxidized with a molecular oxygen-containing gas in a water-containing or aqueous solvent in the presence of a catalyst. The catalysts useful for the above oxidation reaction are those composed of either at least one metal selected from the group consisting of platinum, palladium, rhodium, ruthenium, and rhenium, or the at least one metal admixed with at least one element selected from the group consisting of silver, tellurium, tin, bismuth, lead and indium or with a compound of the at least one element. The resulting pyruvate can be effectively isolated in the form of a solid by concentrating the reaction solution and adding the concentrate to isopropyl alcohol. |
