Abstract: Novel coated catalysts and a process for their preparation by atomizing a mixture of water and a vanadium-V compound, with or without other metal compounds, and applying this mixture to carrier particles which are themselves in motion, drying the coating and subjecting the catalyst particles, which are themselves in motion, to repeated brief treatment with a flame or plasma, followed by rapid cooling, defined temperatures and rates of coating being employed. The catalysts may be used with advantage for the preparation of anthraquinones by oxidation of indans.

Abstract: O.Z. 32,051 Catalysts which consist of a molded carrier, the surface of which is coated with an active catalyst composition of the general formula Mo12AaBbCcDdOx, where A is V and/or W, B is Cu and/or Fe and/or Mn and/or Ni and/or Cr, C is Nb and/or Ta and/or Bi and/or Sb and/or Sn and/or Th and/or Ce and/or U, D is Li and/or Na and/ or K and/or Rb and/or Cs and/or T1 and a is from 0.1 to 18, b is from O to 8, c is from O to 10, d is from O to 2 and x is from 36 to 135, which are particularly active and selective for the oxidation of acrolein and methacrolein with oxygen-containing gases to give acrylic acid and methacrylic acid, respectively, are obtained by first manufacturing the catalyst composition, before applying it to the carrier, from thermally easily decomposed salts of the components by mixing aqueous solutions, slurries or moist solid masses of the salts of the components, drying the mixture and calcining the dried composition at from 140 to 600.degree.C, then milling it to a particle size of less than 150/um and thereafter applying it, as a mixture with water, as a layer from 10 to 1,500 um thick, to the premolded carrier, which has a rough surface.

Abstract: Aromatic nitriles, in particular phthalodinitriles, are prepared from an appropriately alkyl-substituted aromatic hydrocarbon by catalytic oxidation with oxygen or an oxygen-containing gas in the presence of ammonia at elevated temperatures in the vapor phase, in the presence of a catalyst which contains from 2 to 10% by weight of vanadium(V) oxide, from 1 to 10% by weight of antimony(III) oxide, from 0.02 to 2% by weight of an alkali metal oxide and alumina, by a process in which from 0.01 to 1.0% by weight of an alkaline earth metal, or of a compound of an alkaline earth metal, in particular barium or a barium compound, is added to the catalyst.
