Description

  

  Verfahren zur Darstellung einer Verbindung mit hydriertem Ringsystem.         Gegenstand    dieses Zusatzpatentes ist ein  Verfahren zur Darstellung einer Verbindung  von folgender Konstitution  
EMI0001.0002     
    welches dadurch gekennzeichnet ist, dass man       Äthylidenaceton    mit     Cyclopentadien    konden  siert. Die neue Verbindung soll zur Herstel  lung von     Farbstoffen,    pharmazeutischen Pro  dukten und Riechstoffen verwendet werden.

    <I>Beispiel:</I>  84 Gewichtsteile     Äthylidenaceton        (CHs-          CH=CH-CO--CHs)    und 99 Gewichtsteile  frisch destilliertes     Cyclopentadien    werden in  einem Druckgefäss 5 Stunden auf<B>1500</B> er  hitzt. Die schwach     grünlichgelb    gefärbte  Flüssigkeit wird im Vakuum destilliert. Die    Hauptfraktion siedet von 76-80  C, bei  13 min Druck. Sie stellt ein wasserhelles,       kampherartig    riechendes, bewegliches Öl dar.



  Process for the preparation of a compound with a hydrogenated ring system. The subject of this additional patent is a method for the preparation of a compound of the following constitution
EMI0001.0002
    which is characterized in that ethylideneacetone is condensed with cyclopentadiene. The new compound will be used to manufacture dyes, pharmaceutical products and fragrances.

    <I> Example: </I> 84 parts by weight of ethylidene acetone (CHs- CH = CH-CO - CHs) and 99 parts by weight of freshly distilled cyclopentadiene are heated to <B> 1500 </B> in a pressure vessel for 5 hours. The pale greenish yellow colored liquid is distilled in vacuo. The main fraction boils at 76-80 ° C. at a pressure of 13 minutes. It represents a water-white, camphor-like smelling, mobile oil.
