Description

  

      Terfahren    zur Herstellung eines     chromhaltigen        Farbstoffes.       Es wurde gefunden, dass ein neuer     chrom-          lialtiger    Farbstoff erhalten wird, wenn man  den     Azofarbstoff,    welcher durch Kuppeln  der     Diazoverbindung    der     1-Oxynaphthalin-2-          amino-8-sulfamid-4-sulfosäure    mit 2 -     Oxy        -          naphthalin    - 6 -     sulfamid    hergestellt werden  kann, mit     Fluorchrom    behandelt.

   Der so er  haltene Farbstoff bildet ein dunkles Pulver,  das sich in Wasser mit blauer Farbe löst. Er  - färbt Wolle aus saurem Bade in sehr egalen  blauen Tönen von hervorragenden Echtheits  eigenschaften.  



  <I>Beispiel:</I>  51,8 Teile des Farbstoffes aus     diazotier#          ter    1-     Oxynaplithalin-2-amino-8-sulfamicl-4-          stilfosätire    und     2-Oxynaphthalin-6-sulfamicl     löst man kochend in 800 Teilen Wasser. Man  versetzt hierauf mit einer     Fluorchromlösung          entsprechend-    16 Teilen     Crz03,    kocht unter    Zusatz von Glaspulver längere Zeit am Rück  ilusskühler und scheidet dann die Chromver  bindung durch Eindampfen und     Aussalzen     ab.



      The process of producing a chromium-containing dye. It has been found that a new chromium-lialtiger dye is obtained if the azo dye, which is obtained by coupling the diazo compound of 1-oxynaphthalene-2-amino-8-sulfamide-4-sulfonic acid with 2-oxy-naphthalene-6-sulfamide can be made treated with fluorochrome.

   The dye thus obtained forms a dark powder that dissolves in water with a blue color. It - dyes wool from an acid bath in very even blue tones with excellent fastness properties.



  <I> Example: </I> 51.8 parts of the dye from diazotized 1- oxynaplithalin-2-amino-8-sulfamicl-4- stilfosätire and 2-oxynaphthalene-6-sulfamicl are dissolved in 800 parts of boiling water. A fluorochrome solution corresponding to 16 parts of Crz03 is then added, the mixture is boiled for a long time on the reflux cooler with the addition of glass powder and the chromium compound is then separated off by evaporation and salting out.
