  Verfahren zur Herstellung eines kupferhaltigen     Disazofarbstoffes.            Gegenstand    des vorliegenden Zusatz  patentes ist ein Verfahren zur     Darstellung     eines kupferhaltigen     Disazafarbstoffes,    wel  ches dadurch gekennzeichnet ist,     dass    man       diazotierte        3-Amino-4-oxy-1,1'-,diphenylsul-          fon-3'-sulfansäure,        Üiazotiertes        4-Methyl-3-          amino-1,1'-.diphenylsulfon,        Resorcin        und    ein  kupferabgebendes Mittel aufeinander ein  wirken lässt.

    



  Der neue     Farbstoff    stellt ein dunkel  braunes Pulver dar, welches in Wasser mit  gelbstickig brauner, in Schwefelsäure mit       oranger    Farbe löslich     ist        und    Seide in gelb  stickig braunen Tönen von     ,guten        Eehtheiten     anfärbt.  



  <I>Beispiel:</I>  32,9     Gewichtsteile        3-Amino-4-oxy-1,1'-.di-          phenylsulfarn-3'-sulfonsäure    werden mit 6 Ge  wichtsteilen Soda in Wasser gelöst, mit  6,9     Gewichtsteilen        Natriumnitrit    vermischt  und durch     Einlaufenlassen    im 23 Gewichts  teile Salzsäure bei 5      diazotiert.    Man     ver-          einigt,den    zum Teil ausgefallenen     Diazokör-          per    bei     laugenalka.lischer    Reaktion mit 11 Ge-         wichtsteilen        1,

  3-Dioxybenzol.    Der sauer     .ab-          getrennte        Monoazafarb@stoff    wird zur Über  führung in die     Kupferkomplexverbindung     während 30 Minuten mit 25     Gewichtsteilen          kristallisiertem    Kupfersulfat bei 90  ver  rührt,     ausgasalzen,    abgeschieden und     wieder     angerührt.

   Man kuppelt dann     essigsauer    mit  der     Diazoverbindung    aus 24,7     Gewichtsteilen          4-Methyl-3-amino-1,1'-diphenylsulfon        und     scheidet den kupferhaltigen     Disazofarbstoff     mit Kochsalz ab. Er färbt animalische Fasern  in     gelbstichig        braunen    Tönen von     hervor-          ragender    Licht-     und        Was,che,ahthe@t.     



       Anstatt    die     Kupferung    mit dem     Monoazo-          farbstoff    vorzunehmen, kann man auch den  fertig     gebildeten        Disazo,farbstoff    in die  Kupferverbindung     überführen.  



  Process for the preparation of a copper-containing disazo dye. The subject of the present additional patent is a process for the preparation of a copper-containing disaza dye, wel Ches is characterized in that diazotized 3-amino-4-oxy-1,1 '-, diphenylsulfon-3'-sulfanic acid, Üiazotierter 4-methyl -3- amino-1,1 '-. Diphenyl sulfone, resorcinol and a copper-releasing agent can act on each other.

    



  The new dye is a dark brown powder, which is soluble in water with a yellowish-brown color, in sulfuric acid with an orange color and dyes silk in yellow, sticky-brown shades of good consistency.



  <I> Example: </I> 32.9 parts by weight of 3-amino-4-oxy-1,1 '-. Diphenylsulfarn-3'-sulfonic acid are dissolved with 6 parts by weight of soda in water, with 6.9 parts by weight Sodium nitrite mixed and diazotized by running in 23 parts by weight of hydrochloric acid at 5. It is agreed that the partially precipitated diazo bodies in an alkali-alkali reaction with 11 parts by weight of 1,

  3-dioxybenzene. The acidic .ab- separated monoaza dye is for conversion into the copper complex compound for 30 minutes with 25 parts by weight of crystallized copper sulfate stirred at 90, degassed, separated and stirred again.

   It is then coupled in acetic acid with the diazo compound from 24.7 parts by weight of 4-methyl-3-amino-1,1'-diphenyl sulfone and the copper-containing disazo dye is separated off with sodium chloride. It dyes animal fibers in yellowish brown tones with excellent light and what, che, ahthe @ t.



       Instead of coppering with the monoazo dye, you can also convert the finished disazo dye into the copper compound.
