Description

  

      Verfahren    zur Darstellung einer Verbindung mit hydriertem Ringsystem.    Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     112ethyltetra-          hydro-benzaldehyds,    welches dadurch gekenn  zeichnet ist, dass man     Akrolein    mit     1sopren     kondensiert. Die neue Verbindung soll zur  Herstellung von     Farbstoffen,    pharmazeuti  schen Produkten und Riechstoffen verwendet  werden.    <I>Beispiel:</I>  Die     Umsetzung    von     Akrolein    mit     1sopren     vollzieht sich glatt im Druckgefäss beim Er  hitzen der Komponenten auf<B>100</B>  .

   Der hier  bei in guter Ausbeute erhaltene blethyl-tetra-         hydrobenzaldehyd    siedet bei 63 bis 641 C  unter einem Druck von 10 mm.



      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 112ethyltetra-hydro-benzaldehyde, which is characterized in that acrolein is condensed with isoprene. The new compound is to be used for the production of dyes, pharmaceutical rule products and fragrances. <I> Example: </I> The conversion of acrolein with 1soprene takes place smoothly in the pressure vessel when the components are heated to <B> 100 </B>.

   The methyl-tetrahydrobenzaldehyde obtained here in good yield boils at 63 to 641 ° C. under a pressure of 10 mm.
