Amorphous V-P Mixed Oxide with P/V = 2.0 as Active Phase for Butane Oxidation

Article abstract of DOI:10.1246/cl.1990.1513

V-P-mixed oxide catalysts prepared by evaporation method was made up of a mixture of an amorphous phase with P/V=2.0 and a crystalline phase of (VO)2P2O7.The amorphous phase, separated from the (VO)2P2O7 particles by dissolving the precursor in boiled water, was found to show essentially the same selectivity and activity per unit surface area for the maleic anhydride formation from butane as the unseparated catalyst.
