Description

  

  Verfahren zur Darstellung einer     Verbindung    mit hydriertem Ringsystem.    Gegenstand dieses     Zusatzpatentes    ist ein  Verfahren zur Darstellung eines neuen     hydro-          aromatischen        AldAyds,    welches dadurch ge  kennzeichnet ist, dass man     1-11Tethyl-hegatrien-          (1    . 3 . 5) mit     Akrolein    kondensiert. Die neue  Verbindung soll zur Herstellung von Farb  stoffen, pharmazeutischen     Produkten    und       Riechstoffen    verwendet werden.  



  <I>Beispiel:</I>  94 Gewichtsteile 1-     Methyl    -     hexatrien      (1.3.5) und 56 Gewichtsteile     Akrolein     werden in einem Druckgefäss eine Stunde auf  <B>1000</B> C erhitzt und darauf sofort destilliert.  Nach einem Vorlauf von unverändertem  Kohlenwasserstoff und     Akrolein    erhält man  eine bei 14 mm Druck zwischen 70<B>0</B> C und         10211    C siedende Fraktion. Sie wird hierauf  noch zweimal destilliert. Man erhält ein  wasserhelles, bewegliches 01 vom Siedepunkt  Kp.     20   <B>1</B>02-103   C.



  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 hydroaromatic AldAyd, which is characterized in that 1-11Tethyl-hegatrien- (1, 3, 5) is condensed with acrolein. The new compound will be used to manufacture dyes, pharmaceutical products and fragrances.



  <I> Example: </I> 94 parts by weight of 1-methyl-hexatriene (1.3.5) and 56 parts by weight of acrolein are heated to <B> 1000 </B> C for one hour in a pressure vessel and then immediately distilled. After an initial run of unchanged hydrocarbons and acrolein, a fraction boiling between 70 ° C. and 10211 ° C. at 14 mm pressure is obtained. It is then distilled twice more. A water-white, mobile 01 with a boiling point of bp 20 <B> 1 </B> 02-103 C. is obtained.
