Abstract: A process for reactivating a vanadium-containing oxidation catalyst, wherein the catalyst is treated first at from 100 DEG to 600 DEG C., with a volatile phosphorus compound in the presence of an oxygen-containing gas, and then at from 50 DEG to 600 DEG C. with sulfur trioxide or a mixture of a volatile sulfur compound and an oxygen-containing gas.

Abstract: A supported catalyst, containing vanadium pentoxide, titanium dioxide, phosphorus, rubidium and any optionally added cesium, with or without zirconium dioxide, in which the catalytic material contains from 1 to 40% by weight of V2O5, from 60 to 99% by weight of TiO2 and/or ZrO2 and, based on the total amount of TiO2, ZrO2 and V2O5, up to 2% by weight of phosphorus and up to 1.5% by weight of rubidium and/or cesium, and which comprises two layers, of which the inner layer contains more than 0.2 and up to 2% by weight of phosphorus, but no rubidium and/or cesium, and the outer layer contains from 0 to 0.2% by weight of phosphorus and from 0.02 to 1.5% by weight of rubidium and/or cesium, the outer layer accounting for from 10 to 90% by weight of the total catalytic material.

Abstract: A process for the continuous isolation of phthalic anhydride and maleic anhydride from the reaction gases obtained by catalytic oxidation of o-xylene or naphthalene with air, wherein the reaction gases are treated with a hydrocarbon of boiling range from 115 DEG to 175 DEG C. as the solvent in a column, and are then treated with an organic solvent of boiling range from 180 DEG to 290 DEG C. in a second column, the phthalic anhydride and maleic anhydride being isolated from the liquid bottom product of the first column.

Abstract: A catalyst for the oxidation of aromatic or unsaturated aliphatic hydrocarbons which contains in the active material from 60 to 99 percent by weight of titanium dioxide and/or zirconium dioxide, from 1 to 40 percent by weight of vanadium pentoxide and up to 6 percent by weight of combined phosphorus, and which contains from 0 to 0.3 percent by weight of phosphorus in the outer layer and more than 0.3 percent up to 6 percent by weight of phosphorus in the remaining catalytic material.
