Abstract: In the production process for acrylic acid through catalytic vapour-phase oxidation of propene, acrylic acid is separated from the vapour-phase oxidation reaction mixture by means of an absorbing agent containing diphenyl, diphenyl ether or dimethyl phthalate and is also extracted from the vapour-phase oxidation acidic water by means of a solvent containing diphenyl, diphenyl ether or dimethyl phthalate.

Abstract: In a separator (11), designed to separate mixtures composed of liquids of various densities, the inflow (12) of the liquid mixture is so arranged and so designed that the inflowing liquid mixture hits an inner wall(16), located opposite the separator outflows, at an angle alpha of 0 DEG - 45 DEG relative to the normal to the container wall. Such a separator can be used in the manufacturing process for acrylic acid through catalytic vapour-phase oxidation of propene.

Abstract: The invention relates to a method for producing alkyl(meth)acrylate by continuous reaction of an aqueous solution containing (meth)acrylic acid obtained directly from gas-phase oxidation by reacting with a straight-chain or branched alkanol with 1 to 6 C atoms or a mixture of two or more thereof in the presence of an esterification catalyst. The inventive method is characterized in that alkanol is introduced into aqueous solution containing (meth)acrylic acid in the form of a gas.

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.
