Title (DE) VERFAHREN ZUR KONTINUIERLICHEN HYDRIERUNG VON CITRAL ZU CITRONELLAL
(EN) METHOD FOR THE CONTINUOUS HYDROGENATION OF CITRAL TO GIVE CITRONELLAL
(FR) PROCEDE D'HYDROGENATION CONTINUE DE CITRAL PERMETTANT L'OBTENTION DE CITRONELLAL
Abstract: front page image
(DE)Beschrieben wird ein Verfahren zur kontinuierlichen Hydrierung von Citral zu Citronellal, bei dem man eine Flüssigphase, in der das Citral gelöst ist und in der Teilchen eines Katalysators suspendiert sind, der zur präferentiellen Hydrierung von Kohlenstoff-Kohlenstoff-Doppelbindungen vor Kohlenstoff-Sauerstoff-Doppelbindungen fähig ist, in Gegenwart eines wasserstoffhaltigen Gases durch eine Vorrichtung führt, welche den Transport der Katalysatorteilchen hemmt.
(EN)A method for the continuous hydrogenation of citral to give citronellal is disclosed, whereby a liquid phase, in which citral is dissolved and the 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 in the presence of a gas comprising hydrogen, said device preventing the transport of the catalyst particles.
(FR)L'invention concerne un procédé d'hydrogénation continue de citral permettant l'obtention de citronellal. Ledit procédé consiste à amener une phase liquide, dans laquelle le citral est dissous et 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.
