Description

  

  Verfahren zur Herstellung eines Kondensationsproduktes aus       1,1,6-Trimethyl-cyclohepten-(2)-aldehyd-(3)    und Aceton.    Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Herstellung eines bis  her unbekannten Kondensationsproduktes aus       1,1,6@Trimethyl-cyclohepten-    (2)     -aldehyd-    (3)  und Aceton, welches dadurch gekennzeichnet  ist, dass man ein Gemisch des     1,1,6-Trimethyl-          cyelohepten-(2)-aldehyds-(3)    und des Acetons  mit einem Kondensationsmittel behandelt.  Das Kondensationsprodukt ist eine bei 93 bis  95  <B>(0,1 ,5</B> mm) siedende, nach Veilchen rie  chende Flüssigkeit, die als Riechstoff ver  wendet werden kann.  



       Beispiel:     100     gr        1,1,6;        Trimethyl-cyelohepten-(2)-          aldehyd-(3)    werden in 200 cm' Aceton gelöst  und mit einer Lösung von 5     gr    Natrium in  75 cm' Methylalkohol versetzt. Das Gemisch  wird nach einiger Zeit mit     Oxalsäure    an  öesäuert und nach dem     Abdestill.ieren    der         Lösungsmittel    in Äther aufgenommen und  mit     Sodalösung    gewaschen. Der     Sdp.    des       Kondensationsproduktes    liegt bei 93 bis 95    (0,15 mm).



  Process for the preparation of a condensation product from 1,1,6-trimethyl-cycloheptene- (2) -aldehyde- (3) and acetone. The present invention relates to a process for the preparation of a previously unknown condensation product from 1,1,6 @ trimethyl-cyclohepten- (2) -aldehyde- (3) and acetone, which is characterized in that a mixture of 1.1 , 6-trimethyl-cyelohepten- (2) -aldehyds- (3) and acetone treated with a condensing agent. The condensation product is a liquid that boils at 93 to 95 mm (0.1.5 mm) and smells of violets and can be used as a fragrance.



       Example: 100 gr 1,1,6; Trimethyl-cyelohepten- (2) -aldehyde- (3) are dissolved in 200 cm 'acetone and mixed with a solution of 5 g sodium in 75 cm' methyl alcohol. After some time, the mixture is acidified with oxalic acid and, after the solvents have been distilled off, taken up in ether and washed with soda solution. The bp of the condensation product is 93 to 95 (0.15 mm).
