Description

  

      Verfahren    zur Herstellung eines     chromhaltigen    Farbstoffes.    Es wurde gefunden, da() eilt     chromhaltiger          Azofarbstoff    erhalten wird, wenn     inan    den       o-Oxy-o-aininoazofarbstoff    aus     2-Amiiionaph-          thalin-G-sulfosäure    und     4-Chlor        -2-aniino-1-          phenol    mit     Chromforiniat    behandelt.

   Der so ,  gewonnene chromhaltige     Azofai'b"#toff    bildet  ein schwärzliches Pulver, dessen     wässerige     Lösungen in dünner Schicht blau und in  dickerer     Seliicht    violett erscheinen. Ei- färbt  Wolle aus saurem Bade in grünen Farbtönen  von ausgezeichneten     Echtheitseigenschaften.     <I>Beispiel:

  </I>  37,7 Teile des     Farbstoffes,    der erhalten       werden        kann    zum Beispiel durch     Kuppeln          von@-Alltlllollaphthahll-G-)LIlfo@iitll'e        init        diazo-          tiertein        4-Cliloi'-2-antitio-l-phenol,    werden in  <B>350</B> Teilen kochendem     Wa"er        geli)st,    mit  einer     Chromfoi'miatlösuiig,        entsprechend    11;

  -l  Teilen     Cr0s,    versetzt und     längere    Zeit am         ltüchfluhktihler    gekocht. Hierauf wird teil  weise eingedampft und durch Zusatz von  Kochsalz die Chromverbindung aasgesalzen.



      Process for the production of a chromium-containing dye. It has been found that () chromium-containing azo dye is quickly obtained if inan treats the o-oxy-o-amino azo dye from 2-amino-naphthalene-G-sulfonic acid and 4-chloro-2-aniino-1-phenol with chromium formate.

   The chromium-containing azofai'b "#toff 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 green shades of excellent fastness properties. <I> Example:

  37.7 parts of the dye which can be obtained, for example, by coupling @ -Alltlllollaphthahll-G-) LIlfo @ iitll'e with diazo-tiertein 4-Cliloi'-2-antitio-1-phenol dissolved in <B> 350 </B> parts of boiling water, with a chromium film, corresponding to 11;

  -l parts of Cr0s, mixed and cooked for a long time on the ltüchfluhktihler. This is then partially evaporated and the chromium compound is aasgesalted by adding table salt.
