Hydroxyacetone oxidation with hydrogen peroxide over acid catalysts
The oxidation of hydroxyacetone with hydrogen peroxide over acid ZrO <sub>2</sub>-SiO <sub>2</sub>, WO <sub>3</sub>/ZrO <sub>2</sub>-SiO <sub>2</sub> and Dowex DR-2030 catalysts at 20-60 °С has been studied. It has been shown that reaction products are acetic and formic acids, methanol hydroperoxides and hydroxymethyl acetate that confirms the ionic mechanism of Baeyer-Villiger reaction. It has been found that Dowex DR-2030 provides selective formation of acetic and formic acids at 60 °C in a flow regime at 25 % excess of H <sub>2</sub>O <sub>2</sub>.
