Title (EN) METHOD FOR PRODUCING TERPENE ALDEHYDES AND TERPENE KETONES
(FR) PROCÉDÉ DE PRÉPARATION D'ALDÉHYDES ET DE CÉTONES TERPÉNIQUES
(DE) VERFAHREN ZUR HERSTELLUNG VON TERPENALDEHYDEN UND -KETONEN
Abstract:
(EN) The invention relates to a method for producing terpene aldehydes and terpene ketones by oxidatively dehydrogenating the corresponding terpene alcohols, comprising or consisting of the following steps: (a) providing terpene alcohols or terpene-alcohol-containing reactants; (b) bringing the starting substances from step (a) in contact with a heterogeneous ruthenium catalyst; (c) heating the mixture from step (b) to at least 150 °C in the presence of oxygen; optionally (d) separating the terpene aldehydes or terpene ketones from the obtained reaction mixture.
(FR) L'invention concerne un procédé de préparation d'aldéhydes et de cétones terpéniques par déshydrogénation oxydative des alcools terpéniques correspondants, comprenant les étapes suivantes, ou en étant constitué : (a) fourniture d'alcools terpéniques ou de matières de charge contenant un alcool terpénique ; (b) mise en contact des substances de départ de l'étape (a) avec un catalyseur hétérogène au ruthénium ; (c) chauffage du mélange de l'étape (b) à au moins 150 °C en présence d'oxygène ; et éventuellement (d) séparation des aldéhydes terpéniques ou des cétones terpéniques du mélange réactionnel obtenu.
(DE) Vorgeschlagen wird ein Verfahren zur Herstellung Verfahren zur Herstellung von Terpenaldehyden und -ketonen durch oxidative Dehydrierung der entsprechenden Terpenalkohole umfassend oder bestehend aus den folgenden Schritten: (a) Bereitstellung von Terpenalkoholen oder Terpenalkohol-haltigen Edukten; (b) Inkontaktbringen der Ausgangsstoffe aus Schritt (a) mit einem heterogenen Ruthenium-Katalysator; (c) Aufheizen der Mischung aus Schritt (b) in Gegenwart von Sauerstoff auf mindestens 150°C; sowie gegebenenfalls (d) Abtrennung der Terpenaldehyde bzw. Terpenketone vom erhaltenen Reaktionsgemisch.
