The possible role of potassium-stabilized formyl species in the gas-phase carbonylation of alkenes on potassium-promoted Ru/γ-Al2O3 catalysts
Abstract
The cocatalytic function of the potassium oxide promoter in Ru/K/Al2O3 catalysts in stabilizing formyl intermediates during synthesis gas (CO + H2) conversions has been concluded from in situ Fourier transform i.r. studies of gas-phase carbonylation experiments at high pressure.
