Description

Verfahren zur Herstellung von Riechstoffen aus Terpenphenolen Wie im Patent 86o 946, dessen Anspruch lautet: Verfahren zur Herstellung von Riechstoffen aus Terpenphenolen, dadurch gekennzeichnet, daß man Terpenphenole katalytisch reduziert und gegebenenfalls die erhaltenen Terpencyclohexanole zu den entsprechenden Ketonen oxydiert, beschrieben ist, stellen die Hydrierungsprodukte von Terpenphenolen wertvolle Riechstoffe dar.Process for the production of fragrances from terpene phenols Like in patent 86o 946, whose claim reads: Process for the production of fragrances from terpene phenols, characterized in that terpene phenols are reduced catalytically and optionally the terpene cyclohexanols obtained to give the corresponding ketones oxidized, is described, the hydrogenation products of terpene phenols are valuable Odoriferous substances.

Wie nun weiter gefunden wurde, sind auch solche hydrierten Terpenphenole bzw. die entsprechenden Ketone für den gleichen Zweck verwendbar, in welchen die Oxygruppe des Cyclohexanrestes veräthert ist, ebenso wie solche, in welchen neben einer Alkoxygruppe noch eine zweite freie oder verätherte Oxygruppe vorhanden ist. Insbesondere haben sich die durch Kondensation von Guajakol und Guäthol und anschließende Hydrierung erhaltenen Verbindungen, nämlich das i-Oxy-2-methOxy-4-camphylcyclohexan und i-Oxy-2-äthoxy-4-camphylcyclohexan als außerordentlich wertvolle, trotz des hohen Siedepunktes stark riechende, dem natürlichen Sandelholzül weitgehend ähnliche Produkte erwiesen. Desgleichen sind die aus diesen Alkoholen erhältlichen Ketone wertvolle Produkte, deren Geruch mehr in Richtung Vetiver liegt.As has now been further found, such are also hydrogenated terpene phenols or the corresponding ketones can be used for the same purpose in which the Oxy group of the cyclohexane residue is etherified, as well as those in which beside an alkoxy group still has a second free or etherified oxy group. In particular, the condensation of guaiacol and guathol and subsequent Compounds obtained by hydrogenation, namely i-oxy-2-methOxy-4-camphylcyclohexane and i-oxy-2-ethoxy-4-camphylcyclohexane as extremely valuable, despite the has a strong smelling high boiling point and is largely similar to the natural sandalwood oil Products proven. So are the ketones obtainable from these alcohols valuable products, the smell of which is more towards the vetiver.

Beispiel i iooo Teile i-Oxy-2-methoxy-4-camphylbenzol vom Kp,.e = 205 bis 2i5° (erhältlich durch Kondensation von Guajakol mit Camphen mittels Borfluorid) werden mit 3o Teilen eines hochaktiven Nickelkatalysators bei q0 at und 18o bis 2oo° mehrere Stunden mit Wasserstoff behandelt. Man erhält 87o Teile z-Oxy-2-methoxy-q.-camphylcyclohexan vom Kp 7_8 = igo bis 1g5° als farblose viskose Flüssigkeit mit ausgezeichnetem Sandelholzölgerach.Example iooo parts of i-oxy-2-methoxy-4-camphylbenzene with a boiling point of .e = 205 to 2i5 ° (obtainable by condensation of guaiacol with camphene using boron fluoride) are mixed with 3o parts of a highly active nickel catalyst at q0 at and 18o to 2oo ° treated with hydrogen for several hours. 87o parts of z-oxy-2-methoxy-q.-camphylcyclohexane with a boiling point of 7-8 = igo to 1g5 ° are obtained as a colorless, viscous liquid with an excellent smell of sandalwood oil.

Werden 3oo Teile mit 6oo Teilen Eisessig und 15o Teilen Wasser verrührt und in i bis il/, Stunden i2o Teile Natriumbichromat, in 36o Teilen 500/"iger Schwefelsäure gelöst, bei : 2o bis 25° zugesetzt und noch i Stunde nachgerührt, so erhält man nach Verdünnen mit Wasser, Abtrennen des Öles und fraktionierter Destillation im Vakuum 225 Teile des bei i7ö bis i75° unter q. bis 5 mm Druck siedenden i-Oxo-2-methoxy-q.-camphylcyclohexans mit angenehmem, in Richtung Vetiver gehendem Sandelholzölgeruch.300 parts are stirred with 600 parts of glacial acetic acid and 150 parts of water and in one to one and a half hours I20 parts of sodium dichromate, in 36o parts of 500% sulfuric acid dissolved, added at: 20 to 25 ° and stirred for a further hour, this gives after dilution with water, separation of the oil and fractional distillation in Vacuum 225 parts of that at i7ö to i75 ° below q. i-Oxo-2-methoxy-q.-camphylcyclohexane boiling up to 5 mm pressure with a pleasant smell of sandalwood oil, tending towards vetiver.

In gleicher Weise läßt sich durch Kondensation von Camphen mit Guäthol das i-Oxy-2-äthoxy-4.-camphylbenzol vom Kp" = 215 bis 225° herstellen. Durch Hydrierung erhält man daraus das i-Oxy-2-äthoxy-4-camphylcyclohexan vom Kp4_5 = 2io bis 2i5° mit feinem, starkem Sandelholzölgeruch. Dieses läßt sich in das entsprechende Keton überführen. Ferner lassen sich ähnliche, wenn auch etwas schwächer riechende Verbindungen erhalten, wenn man das Camphen mit Resorcinmonomethyläther, Hydrochinonmonomethyläther, Anisol und Veratrol kondensiert und das Kondensationsprcdukt hydriert und gegebenenfalls zum Keton oxydiert.In the same way, by condensation of camphene with Guäthol the i-oxy-2-ethoxy-4.-camphylbenzene with b.p. "= 215 to 225 °. By hydrogenation the i-oxy-2-ethoxy-4-camphylcyclohexane is obtained therefrom with a boiling point of 4_5 = 2io to 2i5 ° with a fine, strong smell of sandalwood oil. This can be converted into the corresponding ketone convict. Furthermore, similar, albeit somewhat weaker-smelling compounds can be found obtained if the camphene with resorcinol monomethyl ether, hydroquinone monomethyl ether, Anisole and veratrole condensed and the condensation product hydrogenated and optionally oxidized to the ketone.

An Stelle von Camphen können auch Terpene, wie Pinen und Dipenten, zur Verwendung kcrrrren. Es können ferner an Stelle der Terpene Alkohole, z. B. Borneol oder Isoborneol, unter Erhitzen in Gegen#"iart von Aktiverde zur Kondensation mit den gerannten Phenoläthern verwendet werden.Instead of camphene, terpenes such as pinene and dipentene, kcrrrren for use. It can also be used instead of the terpenes alcohols such. B. Borneol or isoborneol, with heating in the form of active earth for condensation be used with the raced phenolic ethers.
