Synthesis of 2-Butanone by Selective Oxidation on Solid Wacker-type Catalysts

The role of adsorption phenomena in the modification of surface reactivity and the change of valence state of vanadium during the catalytic gas-phase selective oxidation of 1-butene to 2-butanone on solid Pd-V₂O₅ Wacker-type catalyst are reported. The behavior of Pd-doped KH₃PV₁Mo₁₁O₄₀ in the same reaction and of supported Pd-V₂O₅ in the oxidative dehydrogenation of the possible intermediate sec-butyl alcohol are also shown.
