Abstract (en)
[origin: DE102012207811A1] Heterogeneously catalyzed gas phase partial oxidation of (meth)acrolein to (meth)acrylic acid using a catalytically active multimetal oxide mass (I) is claimed, where (I) is obtained by hydrothermally treating a mixture of sources of elemental constituents of (I) in the presence of water in a hyperbaric vessel, separating the formed solid material, as precursor, and thermally treating the precursor. Heterogeneously catalyzed gas phase partial oxidation of (meth)acrolein to (meth)acrylic acid using a catalytically active multimetal oxide mass of formula (Mo 1 2V a(X 1>) b(X 2>) c(X 3>) d(X 4>) e(X 5>) f(X 6>) gO n) (I) is claimed, where at least 50 mol.% of X 1>in (I) contains W, and (I) is obtained by hydrothermally treating a mixture of sources of elemental constituents of (I) in the presence of water in a hyperbaric vessel, separating the formed solid material, as precursor, and thermally treating the precursor. X 1> : W, Nb, Ta, Cr and/or Ce; X 2> : Cu, Ni, Co, Fe, Mn and/or Zn; X 3> : Sb, Te and/or Bi; X 4> : one or more alkali metal and/or H; X 5> : one or more alkaline earth metal; X 6> : Si, Al, Ti and/or Zr; a : 1-6; b : 0.2-8; c : 0-18; d, g : 0-40; e, f : 0-4; and n : a number that determines the valence and frequency of elements other than O. Independent claims are included for: (1) the catalytically active multimetal oxide mass (I); and (2) a shell-type catalyst from a carrier body, where the surface of the carrier body is applied with (I) and/or optionally binding agent for the application of (I) on the surface of the carrier body.
