Description

  

  Verfahren zur Darstellung einer Verbindung mit hydriertem Ringsystem.    Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung einer Verbindung  von folgender     Konstitution;:     
EMI0001.0002     
    welches dadurch gekennzeichnet ist, dass man       Chinon    mit     Cyclohexadien-Q1.    3 kondensiert.  Das neue Produkt soll zur Herstellung von       Farbstoffen        Verwendung    finden.  



  <I>. Beispiel:</I>  108 Gewichtsteile     Chinon         erhitzt    man mit  250 Gewichtsteilen     Cyclohexadien        -/A    1 . 3  unter Rückfuss. Nach etwa 15 Minuten ist  die anfangs gelbrote Lösung fast farblos ge  worden. Man destilliert dann das über  schüssige     Cyclohexadien    ab und nimmt den  Rückstand in siedendem' ,     Hexahydrobenzol       auf. Beim Abkühlen kristallisiert das Addi  tionsprodukt in gelblich gefärbten dicken  Nadeln aus.     j,    Es     schmilztlbei@95-96      C.



  Process for the preparation of a compound with a hydrogenated ring system. The subject of this additional patent is a process for the production of a compound of the following constitution:
EMI0001.0002
    which is characterized in that one quinone with cyclohexadiene-Q1. 3 condensed. The new product will be used to manufacture dyes.



  <I>. Example: 108 parts by weight of quinone are heated with 250 parts by weight of cyclohexadiene - / A 1. 3 under the hindfoot. After about 15 minutes, the initially yellow-red solution has become almost colorless. The excess cyclohexadiene is then distilled off and the residue is taken up in boiling hexahydrobenzene. On cooling, the addition product crystallizes out in yellowish colored needles. j, It melts at @ 95-96 C.
