    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: A process is proposed for reprocessing the exhaust gas from a plant for producing hydroxylamine or hydroxylammonium salts by catalytic reduction of nitrogen monoxide with hydrogen for the purpose of utilization of at least a part of the nitrogen monoxide and if appropriate hydrogen present in the exhaust gas for producing hydroxylamine or hydroxylammonium salts, which comprises, in a first separation stage, selectively separating off nitrogen monoxide from the exhaust gas of the plant for producing hydroxylamine or hydroxylammonium salts.
