Description

  

  Verfahren zur Herstellung von     Rieehstoffgemisehen.       Die für die     Riechstoffindustrie    wichtigen       Vetiveröle    sind in letzter Zeit untersucht und  in ihrem chemischen Aufbau aufgeklärt wor  den. Ihre Synthese im technischen     Massstab.       ist aber nicht möglich, da entsprechende Ver  fahren nicht zur Verfügung stehen.  



  Wie nun gefunden wurde, besitzen Ver  bindungen der Formel  
EMI0001.0005     
    und auch deren     kernmethylierte    homologe,  welche im chemischen Aufbau völlig von  dem der natürlichen     Vetiveröle    verschieden  sind, den feinen     holzig-würzig-irisartigen    Ge  ruch der echten     Vetiveröle,    so dass sie als       gleichwertigeAustauschstoffe    eingesetzt wer  den können.  



  Gegenstand des vorliegenden Patentes  ist ein Verfahren zur Herstellung von Riech-    Stoffgemischen, welches dadurch gekenn  zeichnet ist, dass man als Ausgangsstoff min  destens ein     4.4-Dimethyl-4-cyclohegyl-butan     verwendet, das in     2-Stellung    ein Sauerstoff  atom aufweist und den gleichen Geruch be  sitzt, wie natürliches     Vetiveröl.    Als solche  Ausgangsstoffe kommen in Frage das     2-Ogy-          4.4-dimethyl-4-cyclohegyl-butan    sowie das       2-Ogo-4.4-dimethyl-4-cyclohegyl-butan,    deren  Formeln oben angegeben sind,

         Dran    geht von     2-Oxo-4.4-dimethyl-4-phe-          nyl-butan    der Formel-  
EMI0002.0006     
    aus, welches gemäss "Journal of     the        Ameri-          can        Chemical        Society"    51, S. 2542-2547,  durch Kondensation aus     Dlesity        loxyd    und  Benzol in Gegenwart von Aluminiumchlorid  erhältlich ist..

   Diese Verbindung hat,     ebenso     wie das durch Reduktion erhältliche 2-Oxy-         1.4'-dimetbyl-:l-phenyl-butan,    einen in der  F     einparfumerie        unerwünschten        kampferarti-          gen    Geruch.  



       Unterwirft    man nun aber diese Verbin  dung einer     @\,eiteren        l@ata.ly    tischen Reduktion,  so dass der     Benzolkern    vollständig hydriert       wird,    so verliert sie     nicht    nur die     kampfer-          art.ige        Geruchsnote,    sondern nimmt einen  neuen, interessanten und sehr stark an     Veti-          verö    l anklingenden Geruch an, der bei syn  thetisch hergestellten Körpern bisher nicht  beobachtet werden konnte.

   Oxydiert man die  Alkoholgruppe zur     Ketongruppe,    so bleibt  diese Geruchsnote erhalten, ist aber ganz  wesentlich verstärkt..  



  Man kann z. B. 2000 Teile des durch Kon  densation von Benzol mit     Mesityloxyd    mit  tels Aluminiumchlorid erhältlichen     2-Oxo-          dimethyl-4-phenyl-butans,    das zuvor durch       Alkalibehandlung    in der Wärme von rest  lichen Chlorprodukten befreit ist, mit  1000 Teilen eines hochaktiven     Niclzelkataly-          sators    unter Druck von etwa 20-50 Alm.  bei 180-200  mit Wasserstoff behandeln.  Nachdem die Hydrierung durch Aufnahme  von reichlich 4     Mol    Wasserstoff beendet ist,  wird vom Katalysator abgetrennt und der er  haltene Alkohol im Vakuum fraktioniert.

    Man erhält 1930 Teile, d. h. 95 % Ausbeute  an     2-Oxy-4.4'-        dimethyl    - 4 -     cyclohexyl-butan     vom Siedepunkt     124-126'    bei 6-7 mm  Druck.  



  Für die Bildung des     Netons    können  800 Teile des vorgenannten Körpers in  800 Teilen Eisessig und 1200 Teilen Wasser  eingerührt werden. Dazu werden im Verlaufe  von 2 Stunden bei 5-10  1000 Teile 50%ige  Schwefelsäure, in der 400 Teile     Natrium-          bichromat    gelöst sind, einlaufen gelassen.  Man rührt noch 2 Stunden bei 20-25  nach.  verdünnt mit Wasser, nimmt das 01 mit  Benzol auf und wäscht es.

   Bei der     Frak-          tionierung    im     Vakuum    erhält man über  700 Teile, d. h. etwa 87     %    des     2-Oxo-4.4-di-          methyl-4-cyclohexyl-butans    in reiner Form  vom Siedepunkt<B>96-100'</B> bei 4-5 mm  Druck. Sein     Semicarbazon    schmilzt bei 155  bis 157 .      Die beiden genannten Körper     bezw.    die  in     analoger    Weise hergestellten Kernhomo  logen können zusammen oder auch jeder für  sich in den verschiedensten Riechstoff  mischungen verwendet werden, insbesondere  aber auch zum Aufbau von künstlichem       Vetiveröl.  



  Process for the production of ingredient mixtures. The vetiver oils important for the fragrance industry have recently been examined and their chemical structure has been clarified. Your synthesis on a technical scale. is not possible, however, as the corresponding procedures are not available.



  As has now been found, compounds have the formula
EMI0001.0005
    and also their nuclear methylated homologues, which are completely different in chemical structure from that of the natural vetiver oils, the fine woody-spicy-iris-like odor of the real vetiver oils, so that they can be used as equivalent substitutes.



  The subject of the present patent is a process for the production of odorous substance mixtures, which is characterized in that the starting material used is at least one 4,4-dimethyl-4-cyclohegyl-butane, which has an oxygen atom in the 2-position and the same It has a smell like natural vetiver oil. Possible starting materials of this type are 2-Ogy-4,4-dimethyl-4-cyclohegyl-butane and 2-Ogo-4,4-dimethyl-4-cyclohegyl-butane, the formulas of which are given above,

         It starts with 2-oxo-4.4-dimethyl-4-phenyl-butane of the formula
EMI0002.0006
    from which, according to "Journal of the American Chemical Society" 51, pp. 2542-2547, is obtainable by condensation from dlesity oxide and benzene in the presence of aluminum chloride.

   This compound, like 2-oxy-1,4'-dimethyl-: 1-phenyl-butane, which can be obtained by reduction, has a camphor-like odor which is undesirable in perfumery.



       But if this compound is subjected to a @ \, pus l@ata.ly tic reduction, so that the benzene nucleus is completely hydrogenated, it not only loses the camphor-like odor note, but takes on a new, interesting and very strong one an odor reminiscent of vetiver oil, which up to now has not been observed in synthetically manufactured bodies.

   If the alcohol group is oxidized to the ketone group, this odor note is retained, but is significantly increased.



  You can z. B. 2000 parts of the 2-oxodimethyl-4-phenyl-butane obtainable by condensation of benzene with mesityl oxide with means of aluminum chloride, which has previously been freed from residual chlorine products by heat treatment with alkali, with 1000 parts of a highly active nickel catalyst treat with hydrogen under pressure of about 20-50 Alm. at 180-200. After the hydrogenation has ended by the uptake of a good 4 mol of hydrogen, the catalyst is separated off and the alcohol it is kept is fractionated in vacuo.

    1930 parts are obtained, i.e. H. 95% yield of 2-oxy-4,4'-dimethyl-4-cyclohexyl-butane with a boiling point of 124-126 'at 6-7 mm pressure.



  To form the neton, 800 parts of the aforementioned body can be stirred into 800 parts of glacial acetic acid and 1200 parts of water. For this purpose, in the course of 2 hours at 5-10,000 parts of 50% strength sulfuric acid, in which 400 parts of sodium bichromate are dissolved, are allowed to run in. The mixture is stirred for a further 2 hours at 20-25. diluted with water, absorbs the oil in benzene and washes it.

   Fractionation in a vacuum gives over 700 parts; H. about 87% of the 2-oxo-4,4-dimethyl-4-cyclohexyl-butane in pure form with a boiling point of <B> 96-100 '</B> at 4-5 mm pressure. Its semicarbazone melts at 155 to 157. The two bodies mentioned respectively. the core homologues produced in an analogous manner can be used together or individually in a wide variety of fragrance mixtures, but in particular also for the construction of artificial vetiver oil.
