Abstract: Improved multi-metal oxide catalysts are obtained by mixing a finely divided mixed oxide of copper (Cu) and other elements at \} 70 deg C with an aqueous solution containing sources of molybdenum (Mo), vanadium (V) and other elements. A process for the production of multi-metal oxide materials of formula: ApBq (I); (where: A = Mo12Va(X )b(X )c(X )d(X )e(X )f(X )gOx; B = (X )12CuhHiOy; X = tungsten, niobium, tantalum, chromium and/or cerium; X = copper, nickel, cobalt, iron, manganese and/or zinc; X = antimony and/or bismuth; X = lithium, sodium, potassium, rubidium, caesium and/or hydrogen; X = magnesium, calcium, strontium and/or barium; X = silicon, aluminium, titanium and/or zirconium; X = molybdenum, tungsten, vanadium, niobium and/or tantalum; a = 1-8; b = 0.2-5; c = 0-23; d = 0-50; e = 0-2; f = 0-5; g = 0-50; h = 4-30; i = 0-20; x, y are determined by the valency and frequency of the elements other than oxygen;) involves preparing the mixed oxide (B) in finely-divided form (starting material 1), mixing in required weight ratio (p : q) (where: p, q are numbers other than zero, such that p:q = (160:1)-(1:1); with an aqueous solution containing sources of elements of component (A) in given stoichiometry ratios (without oxygen; material 2), then drying the mixture and calcining at 250-600 deg C before or after shaping to the required catalyst geometry. Independent claims are also included for: (a) multi-metal oxide materials obtained by the process; (b) an aqueous solution of (A), obtained by dissolving the various sources in water at a temperature (TL) of \- 60 deg C and then cooling to a lower temperature (TE); (c) the solid obtained by drying the solution.

Abstract: Multi-metal oxide compsn. of general formula ÄAÜpÄBÜq (I) is new (where, A = Mo12Va(X b)(X c)(X d)X e)(X f )(X g)Ox, B = X 12CuhHiOy (promoter phase); X = W, Nb, Ta, Cr and/or Ce; X = Cu, Ni, Co, Fe, M n and/or Zn; X = Sb and/or Bi; X = Li, Na, K, Rb, Cs and/or H; X = Mg, Ca, Sr and/or Br; X = Si, Al, Ti and/or Zr; X = Mo, W, V, Nb and/or Ta; a = 1-8; b = 0.2-5; c = 0-23; d = 0-50; e = 0-2; f = 0-5; g = 0-50; h = 4-30; i = 0-20; x, y = values determining the valency and frequency of elements different from oxygen in the compsn.; and p, q = values other than zero, whose ratio p/q = 160-1:1. The proportions of (A)p and (B)q are in the form of chemical compsns. differing from their local environment. A and B are distributed relative to each other such as a mixt. of finely divided A and finely divided B, with the proviso that B contains crystals B* of oxometallates of formula CuMoaWbVcNbdTeOy (II) (where, a/(A+B+C+D+E)=0.7-1.3; (B+C+D+E)/A = 0.01-1; and Y = a value determined by the valency and frequency of elements in (II) different from oxygen) of a new structure type (HT-Cu molybdate) defined by the X-ray diffraction pattern: d(A)=6.79+/-0.3; 3.56+/-0.3; 3.54+/-0.3, 3.40+/-0.3; 3.04+/-0.3, 2.96+/-0.3; 2.67+/-0.2; 2.66+/-0.2; 2.56+/-0.2, 2.36+/-0.2; 2.35+/-0.2; 2.27+/-0.2; 2.00+/-0.2;1.87+/-0.3; 1.70+/-0.2; 1.64+/-0.2; 1.59+/-0.2; 1.57+/-0.2; 1.57+/-0.2; 1.55+/-0.2; 1.51+/-0.2; 1.44+/-0.2. Also claimed are: (i) the oxometallates of formula (II); (ii) mixt. of oxometallates (II); (iii) prodn. of the multi-metal oxide compsn..
