Abstract: On the separation of acrylic acid from reaction gases from the oxidation of propylene or acrolein a countercurrent absorption is carried out with at least 8 parts by weight of carboxylic ester per part by weight of acrylic acid contained in the reaction gas, the dissolved acetic acid and the dissolved water are substantially completely expelled from the resulting absorption solution at elevated temperature by means of inert gases, the loaded inert gases are passed to the countercurrent absorption for the recovery of the acrylic acid contained therein, and the acrylic acid is distilled off under reduced pressure from the carboxylic ester solution which is free from acetic acid and water.

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: Oxidation catalysts which in addition to oxygen ions, with or without NH4+ ions, con molybdenum, tungsten, phosphorus and antimony as basic components, in the atomic ratio Mo:W:P:Sb =12:0.1-3: 0.1-4:0.1-3, and which are prepared in a conventional manner by combining molybdenum, phosphorus, antimony and tungsten compounds in aqueous solutions or suspensions, removing the water and calcining the residues, the combination being carried out at chloride ion concentrations of less than 0.3 mole per mole of molybdenum and in the presence of ions of monocarboxylic acids of 1 or 2 carbon atoms, dicarboxylic acids or hydroxycarboxylic acids, are particularly suitable for the gas phase oxidation of methacrolein to methacrylic acid.
