Abstract: Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing tungsten, vanadium and molybdenum plus optionally one or more of Fe, Mn, Cu, Sn, Sb, Cr, Ce, U, Co, Ni, Zn, Mg or mixture thereof have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, acrolein is oxidized to acrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable by-products.

Abstract: Improved oxidation catalysts containing mixed oxides of vanadium and phosphorus which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapour phase to produce excellent yields of maleic anhydride with very good selectivity, are prepared by a process in which at least one vanadium compound, a substantial portion of which is in the pentavalent state, and at least one phosphorus-containing compound is added to an organic liquid medium capable of reducing at least a portion of the vanadium to a +4 valence state, to form a reaction mixture. Partial reduction of the vanadium is effected in the presence of the phosphorus-containing compound and a highly ordered and uniform mixed vanadium phosphorus oxide-containing catalyst precursor is formed. An oxidation catalyst comprising the mixed oxides of vanadium and phosphorus characterized by an average valence state of vanadium from +3.9 to +4.6, and a phosphorus to vanadium ratio of 1 : 1 to 1.2 : 1, wherein the macrostructure of the catalyst predominantly comprises generally spheroid particles consisting of stacks of integrally associated sheets of catalytic material is also disclosed.

Abstract: A process for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapour phase to produce high yields of maleic anhydride with good selectivity comprises introducing a vanadium compound into an olefinic halogenated organic liquid medium, adding a phosphorus-containing compound to the medium reducing at least a portion of the vanadium to a +4 valence state either prior to or subsequent to the addition of the phosphorus-containing compound, and recovering, drying and calcining the resulting vanadium-phosphorus oxide catalyst precursor.

Abstract: A process is provided for the preparation of fluid bed oxidation catalysts containing the mixed oxides of vanadium and phosphorus, comprising the steps of preparing the catalyst precursor, comminuting the precursor, introducing the precursor into water to form an aqueous slurry and spray drying the slurry. The resulting microspheroidal particles are excellent fluid bed catalysts for the preparation of maleic anhydride from 4-carbon atom hydrocarbons.
