Abstract: A process for the catalytic gas-phase oxidation of propene to acrylic acid, in which the reaction gas starting mixture is oxidized, with an increased propene loading, in a first reaction stage, over a first fixed-bed catalyst and then the acrolein-containing product gas mixture of the first reaction stage is oxidized, in a second reaction stage, with an increased acrolein loading, over a second fixed-bed catalyst, the catalyst moldings in both reaction stages having an annular geometry.

Abstract: Production of acrolein or acrylic acid by gas-phase oxidation of propene comprises passing a mixture of propene, oxygen and inert gas (including at least 20 vol.% nitrogen) through a first fixed bed of catalyst at a temperature (T1) of 300-330 deg C and then through a second fixed bed of catalyst at a temperature (T2) of 300-365 deg C, where T2 is at least 5 deg C above T1. The molar ratio of oxygen to propene is at least 1:1. The catalyst is a mixed metal oxide comprising (i) molybdenum and/or tungsten and (ii) bismuth, tellurium, antimony, tin and/or copper. The propene supply rate is at least 160 Nl per liter of catalyst per hour. The single-pass propene conversion is at least 90%, with at least 90% selectivity for acrolein plus acrylic acid. The propene conversion in the first bed is 40-80%.

Abstract: The invention relates to a method for producing multi-metal oxide masses containing Mo, V, Cu and at least one of the elements W, Nb, Cr and Ce. In this method, a solid component with fine particles is formed and incorporated, at low temperature, in an aqueous solution of parent compounds of the residual multi-metal oxide constituents. The mixture is dried and then burnt.

Abstract: In a process for the preparation of acrolein and/or acrylic acid from propane, the propane is subjected, in a first reaction stage, to a partial oxydehydrogenation with molecular oxygen under homogeneous and/or heterogeneous catalysis to give propene and the product gas mixture formed in the first reaction stage is then used for the preparation of acrolein and/or acrylic acid by gas-phase catalytic propene oxidation.

Abstract: Disclosed is a method for selective hydrogenation of citronellal to form citronellol, wherein a liquid phase in which the citronellal is dissolved and in which particles of a catalyst are suspended, said catatalyst resulting in preferential hydrogenation of carbon-oxygen double bonds in relation to carbon carbon bonds, is guided in the presence of a gas containing hydrogen through a device which inhibits the transport of the catalyst particles.

Abstract: A process is described for selectively hydrogenating citronellal to citronellol in which a liquid phase, in which the citronellal is dissolved and particles of a catalyst are suspended which is capable of preferentially hydrogenating carbon-oxygen double bonds over carbon-carbon double bonds, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.
