Description

  

  Verfahren zur Darstellung einer Verbindung mit hydriertem Ringsystem.    Gegenstand     dieses    Zusatzpatentes ist ein  zerfahren zur Darstellung eines neuen     unge-          ättigten    hydroaromatischen Aldehyds,     wel-          hes    dadurch gekennzeichnet ist, dass man       Lkrolein    mit     a-Phellandren    kondensiert. Die       eue    Verbindung soll zur Herstellung von       'arbstoffen,    pharmazeutischen Produkten und  Riechstoffen verwendet werden.  



  <I>Beispiel:</I>  10 Gewichtsteile     Akrolein    werden mit  2 Gewichtsteilen     a-Phellandren    auf     10011          rhitzt.    Die Vakuumdestillation des     Reak-          !onsgemisches    liefert unter 12 mm Druck  ei<B>128-1300</B> den nahezu reinen Aldehyd,    der durch nochmalige Destillation vollkommen  rein erhalten wird, wie die andern Aldehyde  ein wasserhelles Öl ist und sich durch einen  eigentümlichen Geruch auszeichnet.



  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 in that Lkrolein is condensed with α-Phellandren. The new compound is said to be used in the manufacture of odorants, pharmaceutical products and fragrances.



  <I> Example: </I> 10 parts by weight of acrolein are carved onto 10011 with 2 parts by weight of a-Phellandren. The vacuum distillation of the reaction mixture under 12 mm pressure yields the almost pure aldehyde, which is obtained completely pure by further distillation, like the other aldehydes, which is a water-white oil and has a peculiarity Smell.
