Résumé
Methane is oxidized in aqueous solution with atmospheric oxygen and hydrogen peroxide in a reaction catalyzed by a NaVO3-pyrazine-2-carboxylic acid system. Methyl hydroperoxide is selectively formed at 50 degrees C. The turnover number of the catalyst after 24 h amounts to 480, and the yield of methyl hydroperoxide is 24% with respect to H2O2. Formaldehyde and formic acid are mainly formed at 120 degrees C.
