Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 168144.    Verfahren zur Darstellung     eines        Azofarbstofies.       Nach dem im Hauptpatent beschriebenen  Verfahren erhält man einen blauen Acetat  seidenfarbstoff, wenn man     diazotiertes        6-Brom-          2.4-dinitro-l-aminobenzol    mit     1-Aminonaph-          thalin    kuppelt.  



  Wie nun weiter gefunden wurde, erhält  man einen Farbstoff mit ganz ähnlichen  Eigenschaften, wenn man     6-Brom-2.4-dinitro-          1-aminobenzol        diazotiert    und mit     Tetrahydro-          3-methoxy-a-naphthochinolin    der Formel  
EMI0001.0015     
    kuppelt.  <I>Beispiel:</I>  26,2 Teile     6-Brom-2.4-dinitro-l-amino-          benzol    werden in der üblichen Weise diazo-         tiert    und die mineralsäurehaltige     Diazolösung     wird in eine kalte Lösung von 23,5 Teilen       Tetrahydro-3-methoxy-a-naphthochiiiolin    ein  laufen gelassen.

   Man stumpft mit soviel Na  triumacetat ab, bis die Kupplung beendet ist.  Der erhaltene Farbstoff färbt     Acetatseide    klar  grünblau.



      Additional patent to main patent No. 168144. Process for the preparation of an azo dye. According to the process described in the main patent, a blue acetate silk dye is obtained when diazotized 6-bromo-2,4-dinitro-1-aminobenzene is coupled with 1-aminonaphthalene.



  As has now also been found, a dye with very similar properties is obtained if 6-bromo-2,4-dinitro-1-aminobenzene is diazotized and tetrahydro-3-methoxy-a-naphthoquinoline of the formula
EMI0001.0015
    clutch. <I> Example: </I> 26.2 parts of 6-bromo-2,4-dinitro-1-aminobenzene are diazo- tated in the usual way and the mineral acid-containing diazo solution is poured into a cold solution of 23.5 parts of tetrahydro- 3-methoxy-a-naphthochiiiolin run.

   It is blunted with enough sodium acetate until the coupling is complete. The dye obtained gives acetate silk a clear green-blue color.
