    Abstract: PROBLEM TO BE SOLVED: To provide a method for preparing tetrahydrogeranylacetone by selectively hydrogenating pseudoionone, geranylacetone and/or dihydrogeranylacetone.
    SOLUTION: A method for preparing tetrahydrogeranylacetone is disclosed, wherein pseudoionone, geranylacetone and/or dihydrogeranylacetone are (is) contained in a liquid phase, in which particles of a catalyst which is 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.

    Abstract: Distillation column has a dividing wall which divides it into inflow and extraction sections, and upper and lower column zones. The mixture for distillation comprises a vapor feed which enters between the upper and lower inflow sections, between which the side extraction point removes vapor. The inflow and the extraction zones are offset relative too the dividing wall. The vapor feed rate is equal in all zones of the column. The distillation column has a dividing wall (TW) which divides it into an inflow section (2,4), an extraction section (3,5), and common upper (1) and lower (6) column zones. The mixture for distillation is at least partially a vapor feed (F) which enters between the upper and lower inflow sections, and the side extraction point (B) removes vapor between the upper and lower extraction zones. The cross sectional surfaces of the inflow and the extraction zones are set by an offset in the dividing wall. The F-factor is equal in all the zones of the column, defined as the product of the gas flow speed in m/seconds multiplied with the square root of the gas density in kg/m3.
