Transition metal salts of heteropoly acids as palladium co-catalysts for wacker oxidation of butene-1 to MEK

摘要

The transition metal salts of heteropoly acids have been applied as palladium re-oxidants in heterogeneous solid Wacker cat- laysts for the oxidation of butene-1 to tMEK. Silica, γ-alumina and titania were used as supports for the Pd/MeHPMoV_x system. The influence of cations bonded to heteropoly anions and also the effect of the catalysts acidity on the butene-1 to MEK oxidation Have been elucidated.
