Description

  

      Verfahren    zur Darstellung einer Verbindung     anit    hydrierten     Ringsystem.            Cxegerrstarrd    dieses Zusatzpatentes ist ein       Verfahren    zur Darstellung einer Verbindung       voll    folgender     Konstitutiv         i     
EMI0001.0009     
    welches dadurch gekennzeichnet ist,     dali    man       1Vlaleitis < tureariliyclrid    mit     Phenylbutadien    kon  densiert.

   Die neue     Verbindung    soll zur Her  stellung von     Farbstoffen,        pharinazeutisehen     Produkten und     Riechstoffen    verwendet wer  den.  



  <I>Beispiel:</I>  7,5 Gewichtsteile     3Taieitisätireanliydrid    und  10 Gewichtsteile     Phenylbisi:adien    werden  bei     Wasserbadtemperatur    vorsichtig so lange  erhitzt, bis     heftiges        Aufsieden    der     Liisung       das Einsetzen der Reaktion anzeigt.     1ATan     unterbricht das Erwärmen, lässt die Reaktion  zu Ende gehen und erhitzt dann noch   eventuell unter Zusatz einer kleinen Benzol  menge - zur Vervollständigung der Um  setzung etwa 10 Minuten lang     zurn        Siedet).     



  Das     Umsetzungsprodukt    beginnt sich ge  wöhnlich schon in der Wärme als weisse  Kristallmasse abzuscheiden;     beine        Abkühlen     erstarrt das     Cxanze        zii    einem     Kristallkuchen.     



  Zur Analyse wurde die Substanz aus       hoehsiedendern        Ligroin    unter     Benzolzusatz          umkristallisiert    und hierbei in rein weissen,  harten     l'ristallnadeln    vorn Schmelzpunkt 12U"  (nach     kurzem    Sintern) erhalten.  



  Das     3-Pheuyl-0'-cis-o-tetraliydroplital-          säureanhydrid    ist in den gebräuchlichsten  organischen Lösungsmitteln auch in der Kälte       gilt    löslich, schwer     dagegen    in Wasser,       Ligroin    Lind     Petroläther.    Brom in Chloroform  wirkt in der Kälte nicht ein.     Permanganat-          Soda    dagegen wird augenblicklich reduziert.      Von siedendem Wasser wird es nicht ohne  weiteres aufgenommen,     leicht    hingegen von       wässerigem        Allzali.  



      Process for the preparation of a compound with a hydrogenated ring system. Cxegerrstarrd of this additional patent is a method for the representation of a connection fully following the constitution i
EMI0001.0009
    which is characterized in that 1Vlaleitis <tureariliyclrid condenses with phenylbutadiene.

   The new compound is to be used to manufacture dyes, pharinazeutisehen products and fragrances.



  <I> Example: </I> 7.5 parts by weight of 3-component anhydride and 10 parts by weight of phenylbisi: adiene are carefully heated at water bath temperature until the solution boils vigorously to indicate the onset of the reaction. 1ATan interrupts the heating, allows the reaction to come to an end and then heats it up, possibly with the addition of a small amount of benzene - to complete the reaction, it boils for about 10 minutes).



  The reaction product usually begins to separate out as a white crystal mass when heated; Upon cooling, the cxanze solidifies into a crystal cake.



  For the analysis, the substance was recrystallized from high-boiling ligroin with the addition of benzene and obtained in pure white, hard crystal needles with a melting point of 12U "(after brief sintering).



  3-Pheuyl-0'-cis-o-tetraliydroplitalic anhydride is soluble in the most common organic solvents, even in the cold, but difficult in water, ligroin and petroleum ether. Bromine in chloroform has no effect in the cold. Permanganate soda, on the other hand, is reduced instantly. It is not readily absorbed by boiling water, but it is easily absorbed by watery Allzali.
