A method for the production of tetrahydrogeranylacetone is disclosed, whereby pseudoionone, geranylacetone and/or dihydrogeranylacetone in the liquid phase, in which particles of a catalyst, for the preferential hydrogenation of carbon- carbon double bonds before carbon-oxygen double bonds, are suspended, is fed through a device along in the presence of a gas comprising hydrogen, said device preventing the transport of the catalyst particles.
L'invention concerne un procédé de production de tétrahydrogéranylacétone, consistant à amener de la pseudoionone, géranylacétone et/ou dihydrogéranylacétone en phase liquide, dans laquelle des particules d'un catalyseur sont en suspension, ledit catalyseur étant apte à l'hydrogénation préférentielle de liaisons doubles carbone-carbone avant des liaisons doubles carbone-oxygène, en présence d'un gaz contenant de l'hydrogène, à travers un dispositif empêchant l'acheminement des particules de catalyseur.
