Description

  

      Verfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, wenn man     diazotierte        4-Sulfo-          2-amino-l-phenol-d-karbonsäure    mit     3-Amino-          riaplithalin-1,8-dikarborisäur#e    vereinigt und  den so erhaltenen     Azofarbstoff    mit chrom  abgebenden Mitteln behandelt. Der neue Farb  stoff stellt ein schwärzliches Pulver dar und  löst sich in Wasser mit grüner, in konzen  trierter Schwefelsäure mit braunbordeauxroter  Farbe.

   Er färbt Wolle aus saurem Bade in  grünen Tönen und gibt im Baumwolldruck,  vorzugsweise in Gegenwart von Chrombeizen,  echte, grüne     Färbungen.     



       Beispiel.     10,7 Teile     3-Aminonaphthalin-1,8-dikarbon-          säure-anhydrid    werden mit Hilfe von 10 Teilen  30      /o        iger    Natronlauge in 150 Teilen Wasser  heiss gelöst, mit 10 Teilen Soda versetzt,  abgekühlt und mit der aus 11,65 Teilen       4-Sulfo-2-aniino-l-phe:-ol-6-karbonsö.ure    herge  stellten     Diazoverbindung    versetzt. Nach er  folgter     Kupplung    wird der Farbstoff     ausge-          salzen,    filtriert und getrocknet.  



  52,6 Teile des     Azofarbstoffes    aus     diazo-          tierter        4-Sulfo-2-amino-l-phenol-6-karbonsäure       und     3-Aminonaphthalin-1,8-dikarbonsäurewer-          den    nun in 1000 Teilen kochendem     Wasser     gelöst, mit einer     Chromfluoridlösung    entspre  chend 22,8 Teilen     Cr?        0s    versetzt und längere  Zeit in Gegenwart von Glaspulver unter       Rückfluss    gekocht.

   Hierauf wird die Lösung  des     chromhaltigen    Farbstoffes etwas einge  dampft und der     Farbstoff    in üblicher Weise       _gewonnen.  



      Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-sulfo-2-amino-1-phenol-d-carboxylic acid is combined with 3-amino riaplithalin-1,8-dicarboric acid and the azo dye thus obtained with chromium releasing agents. The new dye is a blackish powder and dissolves in water with green, in concentrated sulfuric acid with a brown-claret-red color.

   He dyes wool from an acid bath in green tones and gives real, green dyes in cotton printing, preferably in the presence of chrome stains.



       Example. 10.7 parts of 3-aminonaphthalene-1,8-dicarboxylic acid anhydride are dissolved in 150 parts of hot water using 10 parts of 30% strength sodium hydroxide solution, 10 parts of soda are added, the mixture is cooled and 11.65 parts are added 4-sulfo-2-aniino-1-phe: -ol-6-karbonsö.ure produced diazo compound was added. After coupling has taken place, the dye is salted out, filtered and dried.



  52.6 parts of the azo dye from diazotized 4-sulfo-2-amino-1-phenol-6-carboxylic acid and 3-aminonaphthalene-1,8-dicarboxylic acid are now dissolved in 1000 parts of boiling water, with a chromium fluoride solution accordingly 22.8 parts Cr? 0s and refluxed for a long time in the presence of glass powder.

   The solution of the chromium-containing dye is then slightly evaporated and the dye is recovered in the usual way.

PATENTANSPRUCH: Verfahren zur -Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diazotierte 4-Sulfo-2-amino-l-phenol-6-karbon- säure mit 3-Aininonaphthalin-1,8-dikarbon- säure vereinigt und den so erhaltenen Azo- farbstoff mit chromabgebenden Mitteln be handelt. Der neue Farbstoff stellt ein sehwärz- liehes Pulver dar und löst sich in Wasser mit grüner, in konzentrierter Schwefelsäure mit braunbordeauxroter Farbe. PATENT CLAIM: Process for the production of a new dye, characterized in that diazotized 4-sulfo-2-amino-1-phenol-6-carbonic acid is combined with 3-ainonaphthalene-1,8-dicarboxylic acid and the resulting Treated azo dye with chromium releasing agents. The new dye is a black powder and dissolves in water with green, in concentrated sulfuric acid with brown-burgundy color. Er färbt Wolle aus saurem Bade in grünen Tönen und gibt im Baumwolldruck, vorzugsweise in Gegen wart von Chrombeizen, echte, grüne Färbungen. He dyes wool from an acid bath in green tones and gives real, green dyeings in cotton printing, preferably in the presence of chrome stains.
