Description

  

  Verfahren zur Herstellung eines Kondensationsproduktes aus       1,1-Dimethyl-cyclohepten-(2)-aldehyd-(3)    und     Nethyläthylketon.       Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Herstellung eines bis  her unbekannten Kondensationsproduktes aus       1,1-Dimethyl-cyclohepten-(2)-aldehyd-(3)    und       Methyläthylketon,    welches dadurch gekenn  zeichnet ist, dass man ein Gemisch des     1,1-          Dimethyl-cyclohepten-(2)-aldehyd-(3)    und des       Methyläthylketons    mit einem Kondensations  mittel behandelt.  



  Das Kondensationsprodukt ist eine bei  100-103   (0,3 mm) siedende Flüssigkeit von  Veilchengeruch und kann als Riechstoff Ver  wendung finden.  



  <I>Beispiel:</I>  100     gr        1,1-Dimethyl-cyclohepten-(2)-alde-          hyd-(3)    werden in 200 cm'     Methyläthylketon     gelöst und mit einer Lösung von 5     gr    Natrium  in 75 cm' Methylalkohol versetzt. Das Gemisch  wird nach einiger Zeit mit     Oaalsäure    ange-    säuert und nach dem     Abdestillieren    der Lö  sungsmittel in Äther aufgenommen und mit       Sodalösung    gewaschen. Der Siedepunkt des       Kondensationsproduktes    liegt bei<B>100-1030</B>  (0,3 mm).



  Process for the preparation of a condensation product from 1,1-dimethyl-cycloheptene- (2) -aldehyde- (3) and ethyl ethyl ketone. The present invention relates to a process for the preparation of a previously unknown condensation product from 1,1-dimethyl-cycloheptene- (2) -aldehyde- (3) and methyl ethyl ketone, which is characterized in that a mixture of 1,1- Dimethyl cycloheptene (2) aldehyde (3) and methyl ethyl ketone treated with a condensation agent.



  The condensation product is a liquid with a violet odor boiling at 100-103 (0.3 mm) and can be used as a fragrance.



  <I> Example: </I> 100 g 1,1-dimethyl-cyclohepten- (2) -alde- hyd- (3) are dissolved in 200 cm 'methyl ethyl ketone and with a solution of 5 g sodium in 75 cm' methyl alcohol offset. After some time, the mixture is acidified with oaal acid and, after the solvents have been distilled off, taken up in ether and washed with soda solution. The boiling point of the condensation product is <B> 100-1030 </B> (0.3 mm).
