Description

  

      Verfahren    zur Darstellung eines     Kondensationsproduktes.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Konden-          sationsproduktes,    welches dadurch     gEkenn-          zeichnet    ist, dass man     Sorbinsäurenitril    mit  2 .     4-Dirnethylbr)tadien    erhitzt. Die neue Ver  bindung soll zur Herstellung vor) Riechstoffen  dienen.  



  <I>Beispiel:</I>  In einem Druckgefäss werden 56 Gewichts  teile     Sorbinsäurenitril    und 83,6 Gewichts  teile     2.4-Dimethylbutadien    4 Stunden auf       17011    C erhitzt. Das Reaktionsgemisch wird  fraktioniert destilliert. Nach einem Vor  lauf, der zur Hauptsache aus unverändertem  Ausgangsmaterial besteht, erhält man eine  Fraktion vom     l@p.        io    108-129 o C (65 Ge  wichtsteile). Die Hauptmenge dieser Fraktion  siedet bei nochmaliger Destillation zwischen  Kp.     io    120-121o C. Die so erhaltene Ver  bindung stellt ein farbloses, stark licht  brechendes Öl dar.



      Process for the preparation of a condensation product. The subject of this additional patent is a process for the preparation of a condensation product, which is characterized in that sorbin nitrile is mixed with 2. 4-Dirnethylbr) tadiene heated. The new connection is intended to be used for the production of fragrances.



  <I> Example: </I> 56 parts by weight of sorbinonitrile and 83.6 parts by weight of 2,4-dimethylbutadiene are heated to 17011 C for 4 hours in a pressure vessel. The reaction mixture is fractionally distilled. After a preliminary run, which mainly consists of unchanged starting material, a fraction of the l @ p is obtained. io 108-129 o C (65 parts by weight). The majority of this fraction boils between bp 120-121o C. when distilled again. The compound thus obtained is a colorless, highly light-refracting oil.
