  • Patent number: 10780428
    Abstract: A process for producing a metal carbonate-containing shaped catalyst body for the hydrogenation of an organic compound having one or more carbonyl group, in which a) a metal carbonate composition which contains, based on the total weight of the metal carbonate composition, from 70 to 94.5% by weight of a metal carbonate mixture containing two or more than two metal carbonates of two or more than two different metals (M), from 5 to 25% by weight of metallic copper, and from 0.5 to 5% by weight of tableting aid is provided, b) a shaped body is formed from the metal carbonate composition provided in step a), and c) the shaped body obtained in step b) is activated in the presence of hydrogen at a temperature in the range from 150 to 250° C.

  • Patent number: 8273925
    Abstract: A method for the production of alkylene oxide addition products comprising (i) charging a stirred reactor with a starting compound capable of adding on or inserting alkylene oxides, introducing at least one alkylene oxide plus a different diluent gas, wherein a portion of said alkylene oxide reacts in a liquid phase with said starting compound, and the remaining alkylene oxide together with said diluent gas forms a gas phase above the liquid phase, (ii) continuously drawing off said liquid phase from the bottom of the reactor via an outlet stub, and recycling to the top of the reactor via an external circulation system, which comprises at least one heat exchanger and at least one Venturi nozzle within said external circulation system, and (iii) metering said gas phase comprising alkylene oxide into said Venturi nozzle via a vacuum line.
