  • Device and method for carrying out heterogeneously-catalysed reactive distillations in particular for the production of pseudoionone
    Patent number: 7476297
    Abstract: A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.
    Type: Grant
    Filed: December 5, 2002
    Date of Patent: January 13, 2009
    Assignee: BASF SE
    Inventors: Gerd Kaibel, Christian Miller, Walter Dobler, Thomas Dirnsteiner, Marcus Sigl, Helmut Jansen, Björn Kaibel
  • Method for the production of tetrahydrogeranylacetone
    Patent number: 7345205
    Abstract: A process is described for preparing tetrahydrogeranylacetone in which pseudoionone, geranylacetone and/or dihydrogeranylacetone in a liquid phase, in which particles of a catalyst which is capable of preferentially hydrogenating carbon-carbon double bonds over carbon-oxygen double bonds are suspended, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.
    Type: Grant
    Filed: July 14, 2003
    Date of Patent: March 18, 2008
    Assignee: BASF Aktiengesellschaft
    Inventors: Hans-Georg Goebbel, Gerd Kaibel, Christian Miller, Walter Dobler, Thomas Dirnsteiner, Thilo Hahn, Klaus Breuer, Werner Aquila
  • Dividing-wall column with feed in whole or in part in the vaporous state and/or side stream take off in whole or in part in the vaporous state
    Patent number: 7264696
    Abstract: A dividing-wall column having a dividing wall which is essentially disposed along the long direction of the column is proposed, which divides the column interior into a feed part, a take off part, an upper shared column part and a lower shared column part, with feed in whole or in part in the vaporous state of a mixture to be separated between the upper region of the feed part and the lower region of the feed part and/or side stream take off in whole or in part in the vaporous state between the upper region of the take off part and the lower region of the take off part, where if feed is in whole or in part in the vaporous state the cross-sectional area of the upper region of the feed part is increased by plane-parallel displacement of the dividing wall toward the upper region of the take off part, and/or if the side stream take off is in whole or in part in the vaporous state, the cross-sectional area of the lower region of the take off part is increased by displacement of the dividing wall toward the lower r
