Description

  

  Verfahren zur Herstellung eines     clironilialtigen        Farbstoffes.       Es wurde gefunden, dass ein     chromhaltiger          AzoFarbstoff    erhalten wird, wenn man den       o-Oxy-o-aminoazofarbstoffaus        ss-Naphthylamin     und     2-Anino-l-oxybenzol-4-sulfosäure    mit       Clii#omliydroxydliydrat    behandelt.

   Der so  gewonnene     chromhaltige        Azofarbstoff    bildet  ein schwärzliches Pulver, dessen wässerige  Lösungen in dünner     Schicht    blau     und    in  dickerer Schicht violett erscheinen.     Ei-        färbt     Wolle aus saurem Bade in satten,     tiefgriinen     Farbtönen von ausgezeichneten     Echtheits-          eigenschaften.     



  <I>Beispiel</I>  35 Teile des     Farbstoffes,    der     erhalten     werden kann zum     Beispiel    durch     linlipcln     von     i3-laplitliylamin    mit     diazoticrtcr        \?-@lminu-          1-oxyberizol-4-sulfosäure    oder durch     Kuplicln     von     @-Naplithylamin        finit        diazotiei#ter        \?-Aniiiio-          1-p-toluolstilfosäureplienolester        -4-sulfosäure          Lind    Verseifen des 

  entstandenen     Farbstoffes,     werden in 350 Teilen     kochendem        Wasser     gelöst,     finit    einer     Chi-omhydroxydb5-dratpaste,            eiitsprechcnd        17.,4    Teilen     Cr    2     0:;,    versetzt und  längere Geit     ain        Itückflusskühler    gekocht.

   Hier  auf wird     filtriert    und teilweise eingedampft  und durch Zusatz von Kochsalz der     chrom-          lialtige        Azofarbstoff        ausgesalzen.  



  Process for the production of a clironilial dye. It has been found that a chromium-containing azo dye is obtained when the o-oxy-o-amino-azo dye is treated from β-naphthylamine and 2-amino-1-oxybenzene-4-sulfonic acid with Clii # omliydroxydliydrate.

   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. Ei- dyes wool from an acid bath in rich, deep green shades with excellent fastness properties.



  <I> Example </I> 35 parts of the dye which can be obtained, for example, by linlipcln of i3-laplithylamine with diazoticrtcr \? - @ lminu- 1-oxyberizole-4-sulfonic acid or by coupling @ -naplithylamine finit diazotiei # ter \? - Aniiiio- 1-p-toluenestilfosäureplienolester -4-sulfonic acid and saponification of the

  The resulting dye is dissolved in 350 parts of boiling water, finely mixed with a chiomohydroxydb5-dratpaste, corresponding to 17., 4 parts of Cr 2 O: ;, and boiled for a longer period in a reflux condenser.

   Here it is filtered and partially evaporated and the chromium-containing azo dye is salted out by adding sodium chloride.
