   PATENTANSPRÜCHE
1. Riechstoffkomposition, gekennzeichnet durch einen Gehalt an einer Verbindung der Formel
EMI1.1     
 worin R den Methallyl- oder Crotylrest darstellt.



   2. Riechstoffkomposition, gekennzeichnet durch einen Gehalt an   3,5,5-Trimethyl-2-(2'-methyl-2'-propenyl)-cyclohex    2-en-1-on.



   Die Erfindung betrifft Riechstoffkompositionen. Diese sind gekennzeichnet durch einen Gehalt an Verbindungen der allgemeinen Formel
EMI1.2     
 worin R den Methallyl- oder Crotylrest darstellt.



   Die neuen Verbindungen können dadurch erhalten werden, dass man das Isophoron der Formel
EMI1.3     
 mit einer Verbindung der Formel
RX   iir    worin R obige Bedeutung hat und X Halogen darstellt, in Anwesenheit einer Base umsetzt.



   Die Umsetzung einer Verbindung der Formel II mit der Verbindung RX kann nach an sich bekannten Methoden durchgeführt werden.



   Als Methallyl- oder Crotylhalogenid kann das Chlorid, Bromid oder Jodid dienen. Bevorzugt ist das Chlorid.



   Als Basen geeignet sind starke Basen, zum Beispiel Alkalimetallalkoholate, z. B. Natriumäthylat, oder anorganische Basen wie Alkalimetallhydroxyde oder Alkalimetallhydride. Bevorzugte Basen stellen Kaliumhydroxyd und Natriumhydrid dar.



   Die Reaktion wird vorzugsweise in einem Lösungsmittel durchgeführt. Geeignete Lösungsmittel sind aromatische Lösungsmittel wie Benzol, Toluol, Xylol usw. Aber auch Methylal kann beispielsweise Verwendung finden.



   Die Reaktion wird vorzugsweise bei erhöhter Temperatur, beispielsweise der   Rückflusstemperatur    des Reaktionsgemisches durchgeführt.



   Die neuen Verbindungen der allgemeinen Formel I und deren Gemische besitzen besondere Riechstoffeigenschaften.



  Sie können deshalb in der   Parfümerieindustrie    zur Herstellung von Parfums und parfümierten Produkten Verwendung finden, beispielsweise zur Parfümierung von Seifen, festen und flüssigen Detergentien, Aerosolen, kosmetischen Produkten aller Art, wieToilettenwasser, Salben, Gesichtsmilch, Schminke, Lippenstiften, Badesalzen und -ölen. In den Parfums bzw. den parfümierten Produkten kann der Gehalt an den Riechstoffen I innerhalb breiter Grenzen, z. B. zwischen etwa   1%    (Detergentien) und etwa 20% (alkoholische Lösungen) liegen. In Parfumbasen bzw. Konzentraten kann er selbstverständlich auch über 20% betragen.



   Die neuen Riechstoffe verfügen im allgemeinen über einen fruchtigen, blumigen, würzigen, etwas an Menthol   ennnemden,    tabakartigen, sehr gut haftenden Geruch.



   Die Riechstoffe der Formel I bzw. deren Isomerengemische können vorteilhaft Riechstoffkompositionen vom Typ Tabak einverleibt werden.



   Die hohe Stabilität der neuen Riechstoffe in den verschiedenartigsten Kompositionen und ihre ausgeprägte Haftfestigkeit prädestinieren sie als Komponenten solcher Kompositionen. Von besonderem Interesse ist die hohe Stabilität der Riechstoffe in Waschmitteln, insbesondere in perborathaltigen   Waschpulvem    und Seifen, wodurch diese Riechstoffe insbesondere zur Parfümierung solcher Waschmittel geeignet sind.



   Synthesebeispiel 1
In einem 2-Liter-Rundkolben, der mit Rührer, Thermometer, Kühler und 500-ml-Trichter versehen ist, gibt man 99 g Methallylchlorid und 138,2 g Isophoron in 600 ml trockenem Toluol. Man erhitzt das Gemisch zum Sieden und gibt nun durch den Trichter während einer Stunde 200 g pulverisiertes Kaliumhydroxyd. Nach beendeter Zugabe lässt man den Kolbeninhalt abkühlen und giesst ihn alsdann auf 500 g zerstossenes Eis. Man trennt die gebildeten Schichten und wäscht die organische Schicht neutral. Man dampft das Lösungsmittel ab, wobei 198,3 g Rohprodukt zurückbleiben, welche einer fraktionierten Destillation unterworfen werden. Siedepunkt des reinen   3,5,5-Trimethyl-2-(2'-methyl-2' -propenyl)-cyclohex-2-    en-1-ons:   102-108"C/5    mm Hg; nD20 = 1,4912;   d420    = 0,9250.

  Geruch: fruchtig, blumig, an Tabak   erinnernd,    gut haftend.



   Synthesebeispiel 2
Auf analoge Art gewinnt man durch Umsetzung von 135 g Crotylbromid und 138,2 g Isophoron 208,8 g rohes 3,5,5-Tri   methyl-2-(2'-butenyl)-cyclohex-2-en-l -on.    Siedepunkt des fraktionierten Materials:   52-54     C/0,02 mm Hg, nD20 = 1,4926;   d420    = 0,9232. Geruch: wie Produkt des Beispiels 1.

   PATENT CLAIMS
1. Fragrance composition, characterized in that it contains a compound of the formula
EMI1.1
 wherein R represents the methallyl or crotyl radical.



   2. Fragrance composition, characterized by a content of 3,5,5-trimethyl-2- (2'-methyl-2'-propenyl) -cyclohex 2-en-1-one.



   The invention relates to fragrance compositions. These are characterized by a content of compounds of the general formula
EMI1.2
 wherein R represents the methallyl or crotyl radical.



   The new compounds can be obtained by using the isophorone of the formula
EMI1.3
 with a compound of the formula
RX iir in which R has the above meaning and X is halogen, is reacted in the presence of a base.



   The reaction of a compound of the formula II with the compound RX can be carried out by methods known per se.



   Chloride, bromide or iodide can serve as methallyl or crotyl halide. The chloride is preferred.



   Suitable bases are strong bases, for example alkali metal alcoholates, e.g. B. sodium ethylate, or inorganic bases such as alkali metal hydroxides or alkali metal hydrides. Preferred bases are potassium hydroxide and sodium hydride.



   The reaction is preferably carried out in a solvent. Suitable solvents are aromatic solvents such as benzene, toluene, xylene, etc. But methylal can also be used, for example.



   The reaction is preferably carried out at an elevated temperature, for example the reflux temperature of the reaction mixture.



   The new compounds of the general formula I and their mixtures have special odor properties.



  They can therefore be used in the perfumery industry for the production of perfumes and perfumed products, for example for perfuming soaps, solid and liquid detergents, aerosols, cosmetic products of all kinds, such as toilet water, ointments, facial milk, make-up, lipsticks, bath salts and oils. In the perfumes or the perfumed products, the content of the fragrances I can be within wide limits, eg. B. between about 1% (detergents) and about 20% (alcoholic solutions). In perfume bases or concentrates, it can of course also be over 20%.



   The new fragrances generally have a fruity, flowery, spicy, somewhat menthol-like, tobacco-like, very well adherent odor.



   The fragrances of the formula I or their isomer mixtures can advantageously be incorporated into fragrance compositions of the tobacco type.



   The high stability of the new fragrances in the most varied of compositions and their pronounced adhesive strength predestine them as components of such compositions. Of particular interest is the high stability of the fragrances in detergents, in particular in perborate-containing washing powders and soaps, as a result of which these fragrances are particularly suitable for perfuming such detergents.



   Synthesis example 1
99 g of methallyl chloride and 138.2 g of isophorone in 600 ml of dry toluene are placed in a 2 liter round-bottom flask equipped with a stirrer, thermometer, condenser and 500 ml funnel. The mixture is heated to the boil and 200 g of powdered potassium hydroxide are then passed through the funnel over the course of one hour. When the addition is complete, the contents of the flask are allowed to cool and then poured onto 500 g of crushed ice. The layers formed are separated and the organic layer is washed neutral. The solvent is evaporated off, 198.3 g of crude product remaining, which are subjected to fractional distillation. Boiling point of pure 3,5,5-trimethyl-2- (2'-methyl-2'-propenyl) -cyclohex-2-en-1-one: 102-108 "C / 5 mm Hg; nD20 = 1.4912 ; d420 = 0.9250.

  Smell: fruity, flowery, reminiscent of tobacco, good adherence.



   Synthesis example 2
In an analogous manner, by reacting 135 g of crotyl bromide and 138.2 g of isophorone, 208.8 g of crude 3,5,5-tri methyl-2- (2'-butenyl) -cyclohex-2-en-l -one are obtained. Boiling point of the fractionated material: 52-54 C / 0.02 mm Hg, nD20 = 1.4926; d420 = 0.9232. Odor: like product of example 1.
