Description

  

      ;,Verfahren    zur Herstellung eines komplex gebundenes Chrom enthaltenden       Azofar        bstoffes.       Es wurde gefunden, dass ein komplexge  bundenes Chrom enthaltender     Azofarbstoff     hergestellt werden kann, wenn der     Azofarb-          stoff    der Formel  
EMI0001.0007     
    mit chromabgebenden Mitteln behandelt wird.

    Die -     neue    Chromverbindung     stellt    ein       grauschwarzes    Pulver dar, das sich in  Wasser, in 10     %        iger        Sodalösung,    sowie in  10     %        iger    Natronlauge mit     braunoranger    und  in     konzentrierter    Schwefelsäure mit gelb  oranger Farbe löst. Sie erzeugt auf anima  lischen     Fasern    braune Töne von sehr     .guten     Echtheitseigenschaften.

      Der dem Verfahren als     Ausgangsstoff     dienende     Azofarbstoff    der obigen Formel  kann -durch Kupplung in alkalischem Me  dium von     diazotierter        2-Amino-1-carboxy-          benzol-5-sulfonsäure    und     5-Aminoperinaphth-          indandion    erhalten     werden.     



  Die     Behandlung    mit chromabgebenden  Mitteln erfolgt nach .den bekannten     Metho-          @den,        beispielsweise    durch Erhitzen in wäs  seriger Lösung mit Salzen des     dreiwertigen     Chroms.  



       Beispiel:     4,4 Teile     des    durch alkalische Kupplung       hergestellten        Azofarbstoffes    aus     diazotierter          2-Amino-il-carbogybenzol-5@sulfonsäure    und       5-A.minoperinaphthindandion    werden in 100  Teilen Wasser .gelöst und mit einer     Chrom-          formiatlösung,    enthaltend     0g83    Teile     Cr2O3,     24     Stunden    zum (Sieden erhitzt.

   Die neue  Chromverbindung wird durch Beigabe von  Kochsalz     abgeschieden,        abfiltriert    und ge  trocknet.



      ;, A process for the preparation of an azo dye containing complexed chromium. It has been found that an azo dye containing complex bonded chromium can be produced if the azo dye of the formula
EMI0001.0007
    is treated with chromium-releasing agents.

    The - new chromium compound is a gray-black powder that dissolves in water, in 10% soda solution, as well as in 10% sodium hydroxide solution with brown-orange color and in concentrated sulfuric acid with yellow-orange color. It produces brown tones with very good fastness properties on animal fibers.

      The azo dye of the above formula serving as starting material for the process can be obtained by coupling in alkaline medium of diazotized 2-amino-1-carboxy-benzene-5-sulfonic acid and 5-aminoperinaphth-indanedione.



  Treatment with chromium-releasing agents takes place according to the known methods, for example by heating in aqueous solution with salts of trivalent chromium.



       Example: 4.4 parts of the azo dye produced by alkaline coupling from diazotized 2-amino-il-carbogybenzene-5 @ sulfonic acid and 5-a-minoperinaphthindanedione are dissolved in 100 parts of water and dissolved with a chromium formate solution containing 0.63 parts of Cr2O3, Heated to boiling for 24 hours.

   The new chromium compound is deposited by adding sodium chloride, filtered off and dried.
