Abstract:
A process for the manufacture of a phosphorus/vanadium/metal oxide catalyst suitable for the oxidation of butane to maleic anhydride can be prepared by reacting in an aqueous medium a vanadium compound, inorganic acid and metal oxide, then adding orthophosphoric acid to form a soluble vanadium phosphorus metal oxide catalyst, removing the acidified water and adding an aliphatic alcohol, removing the alcohol and recovering under vacuum the solid phosphorus vanadium metal oxide catalyst.
