| 概要 |
The reaction mechanism of methylethylketone (MEK) oxidation to acetaldehyde (AcH) and acetic acid (AcOH) which is characterized by the oxidative splitting of carbon skeleton has been investigated over... V_2O_5 catalysts. Kinetics of MEK oxidation at 150℃ over V_2O_5-MoO_3 suggested the participation of molecular oxygen in the reaction. The formation of O_2^- species on the catalyst surface under the reaction conditions was in fact confirmed with temperature programmed desorption and EPR techniques, by using a partially reduced V_2O_5 catalyst supported on silica gel. It was shown that the O_2^- species thus formed reacted with MEK to produce AcH and AcOH selectively, while the lattice oxygen of V_2O_5 converted MEK into CO_2. 0n the basis of these results it was concluded that the O_2^- was the oxygen species reacting with MEK in the oxidative scission reaction.続きを見る
