| titleOfInvention | Mass of metal oxides |
| abstract | FIELD: chemistry. n SUBSTANCE: described is mass of metal oxides, intended as catalyst for heterogeneously-catalysed partial oxidation and/or ammoxidation of at least one saturated and/or unsaturated hydrocarbon, of general stechiometry I MO 1 V a M 1 b M 2 c M 3 d O n (I), were M 1 = stands for Te; M 2 =stands for Nb; M 3 = stands for at least one of elements from group, which includes Pb, Ni, Co, Bi and Pd; a = 0.05 to 0.6, b= 0.01 to 0.5, c= 0.01 to 0.5, d = 0.0005 to 0.5 and n= equals the number determined by valence and number of different from oxygen elements in (I), whose X-ray diffractogragm has diffraction reflexes h, i and k , whose peaks are at diffraction angles (2Θ) 22.2±0.5° (h), 27.3±0.5° (i) and 28.2±0.5° (k), and - diffraction reflex h in the range of X-ray diffractogram is the most intensive and has peak half-width maximal value 0.5°, intensity P i of diffraction reflex i and intensity P k fulfill ratio 0.65≤R≤0.85, in which R is determined by formula R=P i /(P i +P k ) intensity ratio, and - half-width of diffraction reflex i and diffraction reflex k each constitute ≤1°, and at least one mass of metal oxides (I) represents such, X-ray diffractogram of which does not have diffraction reflex with peak position 2Θ=50.0±0.3°. Described is mass of metal oxides, which contains equal or more than 80 wt % of at least one mass of metal oxides, indicated above, and whose X-ray diffractogram has diffraction reflex with peak 2Θ=50.0±0.3°.Also described are methods of heterogeneously catalysed partial gas phase oxidation or ammoxidation of at least one saturated or unsaturated hydrocarbon, using as catalytic active mass at least one mass of metal oxides, described above. Described is method of obtaining metal oxides mass by mixing sources of its elementary components, calcination of dry mixture at 350-700°C and washing by organic and/or inorganic acid solution. n EFFECT: increasing target product selectivity. n 17 cl, 1 tbl, 16 ex, 17 dwg |
