Description

  

  Verfahren zur Herstellung eines     nickelhaltigen        Polyazofarbstoffes    der     Stilbenreihe            Gegenstand    des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     nickel-          haltigen        Polyazofarbstoffes    der     'Stilbenreihe,       welches darin besteht,

   dass man 1     1VIol    der       Aminodisazoverbindung    der Zusammensetzung  
EMI0001.0011     
         diazotiert    und den     Diazokörper    mit 1     lhol     der     Nickelkomplexverbindung    von     2,2',4'-Tri-          oxy-1,1'-azobenzol-5-sulfonsäure    vereinigt.  



  Der neue, nickelhaltige     Polyazofarbstoff     der     Stilbenreihe    ist ein braunschwarzes Pul  ver, welches sich in Wasser mit     violettbrauner       Farbe löst und     Chromvelourleder        in.    violett  stichig braunen,     schleifechten    Tönen färbt.  



  Im nachfolgenden Beispiel bedeuten die  Teile Gewichtsteile, und. die Prozente sind  in Gewichtsprozenten angegeben.    <I>Beispiel</I>       6-1,3    Teile der     Aminodisazoverbindung    der Zusammensetzung  
EMI0001.0026     
    werden in Form des     Natriumsalzes    in<B>1000</B>  Teilen Wasser gelöst     imd    durch Zugabe einer  Lösung von 7 Teilen     Natriumnitrit    in 20 Tei  len Wasser und 30 Teilen     30prozentiger    Salz  säure bei 10      diazotiert.    Die Lösung der     Di-          azoverbindung    lässt man in eine eisgekühlte  <B>Losung</B> von<B>36,

  7</B> Teilen der     Nickelkomplex-          v        erbindung    aus     2,2',4'-Trioxy-1,1'-azobenzol-:j-          sulfonsäure    und     40    Teilen     Natriumcarbonat       in     400    Teilen Wasser fliessen. Nach beendig  ter     Kuppltmg    wird der erhaltene nickelhaltige       Polyazofarbstoff    durch Zusatz von Natrium  chlorid abgeschieden, von der Lösung     abfil-          triert    und getrocknet.

   Er ist ein braunschwar  zes Pulver, löst sich in Wasser mit. violett  brauner Farbe und färbt     Chromvelourleder     in     violettstichig    braunen, schleifechten Tönen.



  Process for the production of a nickel-containing polyazo dye of the stilbene series The subject of the present patent is a process for the production of a nickel-containing polyazo dye of the stilbene series, which consists in

   that one 1 1VIol of the aminodisazo compound of the composition
EMI0001.0011
         diazotized and combined the diazo body with 1 lhol of the nickel complex compound of 2,2 ', 4'-trioxy-1,1'-azobenzene-5-sulfonic acid.



  The new, nickel-containing polyazo dye from the stilbene range is a brown-black powder that dissolves in water with a violet-brown color and dyes chrome suede in violet, brown, abrasive tones.



  In the following example, the parts mean parts by weight, and. the percentages are given in percentages by weight. <I> Example </I> 6-1.3 parts of the aminodisazo compound of the composition
EMI0001.0026
    are dissolved in the form of the sodium salt in 1000 parts of water and diazotized at 10 by adding a solution of 7 parts of sodium nitrite in 20 parts of water and 30 parts of 30 percent hydrochloric acid. The solution of the diazo compound is left in an ice-cold <B> solution </B> of <B> 36,

  7 parts of the nickel complex compound of 2,2 ', 4'-trioxy-1,1'-azobenzene-: j-sulfonic acid and 40 parts of sodium carbonate flow in 400 parts of water. After the coupling has ended, the nickel-containing polyazo dye obtained is deposited by adding sodium chloride, filtered off from the solution and dried.

   It is a brown-black powder that dissolves in water. violet-brown color and dyes chrome suede in violet-tinged brown, abrasive tones.
