Abstract: Sequential production of a library of N different solids (especially heterogeneous catalysts) whereby N reaches an integer >= 2 in one day involves dosing solutions, emulsions and/or dispersions into a mixer and drying the mixture, the ratios in the dosing step being varied and the dosing, drying and variation steps being repeated N-1 times. Sequential production of a library of N different solids (especially heterogeneous catalysts) whereby N reaches an integer >= 2 in one day involves (a) production of (i) >= 2 different sprayable solutions, emulsions and/or dispersions of elements and/or compounds providing chemical elements as solids and optionally (ii) inorganic carrier dispersions; (b) continually dosing the solutions etc. in predetermined ratios into a mixer to give homogeneous mixing; (c) continuously drying the mixture and removing it from the mixer; (d) varying the ratios in step (b) and repeating the steps (b), (c) and (d) N-1 times to recover N different dry mixtures; and (e) optionally forming and optionally calcining the mixtures to yield solids. Independent claims are also included for (1) an apparatus for the sequential production comprising >= 2 vessels for the solutions etc., a mixer, pumps and interconnecting tubes for the vessels and the mixer, a dryer connected to the mixer, and a central computer controlling the pumps and (2) parallel testing of the solids library for desired catalytic properties by separately introducing the individual solids into multi-reactors and then testing them.

Abstract: A heterogeneously catalyzed gas-phase partial oxidation of acrolein to acrylic acid over a catalytically active multimetal oxide material which contains the elements molybdenum and vanadium, tellurium or antimony, and elements consisting of niobium, tantalum, tungsten or titanium, whose X-ray diffraction pattern has no reflections with the peak position 2 theta = 50 +/- 0.30 but has reflections whose peaks are at specified diffraction angles. Heterogeneously catalyzed gas-phase partial oxidation of acrolein to acrylic acid over a catalytically active multimetal oxide material which contains the elements molybdenum and vanadium, tellurium or antimony, and elements consisting of niobium, tantalum, tungsten or titanium, whose X-ray diffraction pattern has no reflections with the peak position 2 theta = 50 +/- 0.30 but has reflections h, i and k whose peaks are at the diffraction angles (2 theta) 22.2 +/- 0.5 degrees (h), 27.3 +/- 0.50 (i) and 28.2 +/- 0.50 (k). The reflection (h ) is the one with the strongest intensity within the X-ray diffraction pattern and having a full width at half height of not more than 0.50; the intensity (Pi) of the reflection (i) and the intensity (Pk) of the reflection (k) fulfill the relationship that R is 0.65-0.85, where R is the intensity ratio defined by the formula R = Pi/(Pi + Pk); and the full width at half height of the reflection (i) and of the reflection (k) is in each case at most 10. The catalytically active multimetal oxide material is of formula (I). Mo1VaM1bM2cM3dOn (I). M1 = element(s) from the group consisting of Te and Sb; M2 = element(s) from the group consisting of Nb, Ti, W, Ta and Ce; M3 = element(s) consisting of Pb, Ni, Co, Bi, Pd, Ag, Pt, Cu, Au, Ga, Zn, Sn, In, Re, Ir, Sm, Sc, Y, Pr, Nd or Tb; a = 0.01-1; b = 0-1; c = 0-1; d = 0-0.5; n = number that is determined by the valency and frequency of the elements other than oxygen in formula (I).

Abstract: A multimetal oxide material contains the elements Mo, V and Te and/or Sb and at least one of the elements Nb, Ti, W, Ta and Ce and promoters and has a specific X-ray diffraction pattern. Moreover, such a multimetal oxide material is used as a catalyst for heterogeneously catalyzed gas-phase partial oxidations of hydrocarbons.
