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: The production of acrylic acid (I) and/or its esters comprises; (a) catalytic gas-phase oxidation of propene and/or acrolein to give a gaseous product containing (I), (b) absorption of the reaction product with a solvent, (c) distillation in a column to give crude (I) and solvent, (d) purification of (I) by crystallisation and optionally (e) esterification of crystallised (I). Also claimed is an apparatus for the process, comprising reactor(s) for stage (a), an absorption column, a distillation column, dynamic crystalliser(s) and static crystalliser(s), and container(s) for intermediate storage.
