Description

  

  Verfahren     zui#    Herstellung eines     ehroiuhaltigeu        Farbstoffes.       Es wurde gefunden, dass ein     chromhaltiger          Azofarbstoff        erhalten    wird,

   wenn man den       o-Oxy-o-aminoazofarbstoff    aus     1-Aminonapli-          tliaiin-4-sulfosäure    und     4-Chlor-2-amino-l-          phenol-5-sulfosäure    mit     Chi-onihytli#oxydhydi#at          behandelt.    Der so gewonnene     chromhaltige          Azofarbstoff    bildet ein schwärzliches Pulver,  dessen wässerige Lösungen in dünner Schicht  blau und in dickerer Schicht violett erschei  nen. Er färbt Wolle aus saurein Bade in  grünen     Farbtönen    von ausgezeichneten     Echt-          heitseigenschaften.     



  <I>Beispiel:</I>  44,6 Teile des Farbstoffes, der erhalten       werden    kann zum Beispiel durch     Kuppeln     von     1-Aniinonaphtlialin-4-sulfosä        ure        finit        diazo-          tierter        4-Chlor-2-ainino-l-plienol-5-sulfosäure,     werden in 800 Teilen Wasser kochend gelöst,  mit einem     Überschuss    einer frisch gefällten  Paste von     Ohromhydroxydhy        drat    versetzt und         1 < Lngere    Zeit     ain        RÜckflnsskühler    gekocht.

   Hier  auf filtriert man vom     unveränderten    Chrom  hydroxydhydrat und dampft das klare Filtrat  zur Trockne.



  Process for the production of a gold-containing dye. It has been found that a chromium-containing azo dye is obtained

   if you treat the o-oxy-o-aminoazo dye from 1-aminonapli- tliaiin-4-sulfonic acid and 4-chloro-2-amino-1-phenol-5-sulfonic acid with Chi-onihytli # oxydhydi # ate. 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 acidic bath in green shades with excellent fastness properties.



  <I> Example: </I> 44.6 parts of the dye which can be obtained, for example, by coupling 1-aniinonaphthlialin-4-sulfonic acid finitely diazoated 4-chloro-2-ainino-1-plienol-5 -sulfonic acid, are dissolved in 800 parts of boiling water, an excess of a freshly precipitated paste of ohromic hydroxide hydrate is added and the mixture is boiled in a reflux condenser for 1 <longer time.

   Here, the unchanged chromium hydroxide is filtered off and the clear filtrate is evaporated to dryness.

PATENTANSPRUCH: Verfahren zur Herstellung eines chrom haltigen Azofarbstoffes, dadurch gekennzeich net, dass man den o-Oxy-o-aniinoazofai-bstoff aus 1-Aminonaphthaliii-4-sulfosäure und 4-Chlor- 2 -aniino -1-plienol - 5 - sulfosäure mit Chrom- bydroxydhydrat behandelt. PATENT CLAIM: Process for the production of a chromium-containing azo dye, characterized in that the o-oxy-o-aniinoazofai-bstoff from 1-aminonaphthaliii-4-sulfonic acid and 4-chloro-2-aniino-1-plienol-5-sulfonic acid treated with chromium hydroxide hydrate. Der so gewonnene cbromlialtige Azofarbstoff bildet ein schwärz liches Pulver, dessen wässerige Lösungen in dünner Scliiclit b'lau und in dickerer Schicht violett erscheinen. Er färbt Wolle aus saurem Bade in grünen Farbtönen von ausgezeichne ten Echtheitseigenschaften. The bromolial azo dye thus obtained forms a blackish powder, the aqueous solutions of which appear blue in thin layers and violet in a thick layer. It dyes wool from an acid bath in green shades with excellent fastness properties.
