Description

  

      Verfahren    zur Darstellung einer     Verbindung    mit hydriertem Ringsystem.    Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines neuen, un  gesättigten,     hydroaromatischen        Aldehydes,     welches dadurch gekennzeichnet ist. dass man       Myrcen    mit     Crotonaldehyd    kondensiert.  Die neue Verbindung soll zur     Herstellung          von        Farbstoffen,    pharmazeutischen Produk  ten und Riechstoffen verwendet werden.  



       Beispiel:     10 Gewichtsteile     TUvrcen    und 10 Gewichts  teile     Crotonaldehyd    werden im Druckgefäss  auf 150   erhitzt. Das     Reaktionsgemisch    wird  der Destillation im     Vakuum        unterworfen,     wobei ein Aldehyd unter<B>1-9</B>     rnm    Druck bei    143 bis 144' als wasserhelles 01 erhalten  wird. Eine nochmalige Destillation liefert ihn  vollkommen rein.



      Process for the preparation of a compound with a hydrogenated ring system. The subject of this additional patent is a process for the preparation of a new, unsaturated, hydroaromatic aldehyde, which is characterized. that myrcene is condensed with crotonaldehyde. The new compound is intended to be used in the manufacture of dyes, pharmaceutical prod ucts and fragrances.



       Example: 10 parts by weight of TUvrcen and 10 parts by weight of crotonaldehyde are heated to 150 in a pressure vessel. The reaction mixture is subjected to distillation in vacuo, an aldehyde being obtained under 1-9 pressure at 143 to 144 'as water-white oil. Another distillation delivers it completely pure.

PATENTANSPRUCH: Verfahren zur Darstellung eines neuen, ungesättigten hydroaromatischen Aldehydes, dadurch gekennzeichnet, dass man Myrcen mit Crotonaldehyd kondensiert. Der so er haltene Aldehyd siedet bei 12 mm Druck bei 143 bis 144' und bildet ein wasser helles 01. PATENT CLAIM: Process for the preparation of a new, unsaturated hydroaromatic aldehyde, characterized in that myrcene is condensed with crotonaldehyde. The aldehyde obtained in this way boils at 143 to 144 'at 12 mm pressure and forms a water-white 01.
