Description

  

      Verfahreu    zur     Herstellung;    eines     clirouihziltiben        Farbstoffes.       <B>Es</B> wurde gefunden, dass ein     chromhaltiger          Azofarbstoff    erhalten wird, wenn man den       o-Oxy        -o-aminoazofarbstoff    aus     P-Naphthyl-          amin    und     2-Amirio-l-oxybenzol-4-sulfosäure     mit     Fluorchrom    behandelt.

   Der so gewonnene  chromhaltige     Azofarbstoff    bildet ein schwärz  liches Pulver, dessen wässerige Lösungen in       dünner    Schicht blau und in     dickerer    Schicht  violett erscheinen. Er färbt Wolle aus saurem  Bade in satten,     tiefgrünen    Farbtönen von  ausgezeichneten Echtheitseigenschaften.

           Beispiel:     35 Teile des     Farbstoffes,    der erhalten       werden    kann zum Beispiel     durch    Kuppeln  von     i3-Naplithylamiri    mit dianotierter     2-Aniino-          1-oxyberizol-4-sulfosäure    oder durch Kuppeln  von     fl-Naphthylamin        finit        dianotierter        2-Amino-          1-li-toluolsulfosäureplienolester-4-sulfosäure     und Verseifen des entstandenen Farbstoffes,

    werden in 350 Teilen     kochendeui        Wasser          geliist,    mit einer     Fluorcliroinlösung,    ent-    sprechend 11,4 Teilen     Cr-2        0a,    versetzt und       Inngere    Zeit am     Rückflusskühler    gelocht.  Hierauf     wird    teilweise eingedampft und durch  Zusatz von     Kochsalz    der chromhaltige     Azo-          farbstoff    aasgesalzen.



      Method of manufacture; of a clirouihziltiben dye. It has been found that a chromium-containing azo dye is obtained if the o-oxy-o-aminoazo dye composed of P-naphthylamine and 2-amino-1-oxybenzene-4-sulfonic acid is treated with fluorochrome.

   The chromium-containing azo dye obtained in this way forms a blackish powder, the aqueous solutions of which appear blue in a thin layer and purple in a thicker layer. It dyes wool from an acid bath in rich, deep green shades with excellent fastness properties.

           Example: 35 parts of the dye which can be obtained, for example, by coupling 13-naplithylamine with dianotated 2-aniino-1-oxyberizole-4-sulfonic acid or by coupling fl-naphthylamine finitely dianotized 2-amino-1-li-toluenesulfonic acid plienol ester -4-sulfonic acid and saponification of the resulting dye,

    are dissolved in 350 parts of boiling water, mixed with a fluoroclinic solution, corresponding to 11.4 parts of Cr-2 0a, and perforated on the reflux condenser within a short period of time. It is then partially evaporated and the chromium-containing azo dye is carburized by adding sodium chloride.
