    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 method for the production of 4-vinylcyclohexene involves dehydrogenation of a feed gas containing n-butane followed by cyclodimerization of the resulting butadiene. A method for the production of 4-vinyl-cyclohexene (VCH) involves: (A) preparation of a feed gas stream containing n-butane; (B) dehydrogenation of the n-butane to give a product stream containing butadiene, n-butane, possibly 1- and 2-butene and possibly water vapor and other components; (C) catalytic dimerization of butadiene in the product stream to give a product stream containing VCH, n-butane and possibly 1-butene, 2-butene and unreacted butadiene; and (D) separation of VCH, with recycling of n-butane etc. to stage (B). Independent claims are also included for: (1) a method (M1) for the production of ethylbenzene (EB) or styrene (S), involving stages (A-D) as above followed by (E) catalytic dehydrogenation of VCH to EB or oxidative dehydrogenation in presence of oxygen to give S; (2) a method (M2) for the production of styrene (S) by (B') feeding a n-butane-containing stream and a VCH-containing stream into a dehydrogenator and dehydrogenating the mixture in presence of oxygen to give a mixture of styrene (S), butadiene, n-butane, 1- and 2-butenes and possibly EB etc., (C') separating the S, EB and other high-boiling by-products, (D') dimerizing the butadiene/butane/butene-containing stream to give a stream containing VCH, butane and butenes etc., (E') separating VCH from this stream and passing it to the dehydrogenator.
