Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          Nitro-2-amino-l-phenol-6-sulfosäure    mit ä  Aminonaphthalin-1,8-dikarbonsäure vereinigt.  Der neue Farbstoff bildet ein     rötlichbraunes     Pulver, das sich in Wasser mit gelbroter, in  Schwefelsäure mit gelber Farbe löst. Er  färbt Wolle aus saurem Bade in     bordeaux     Tönen, welche beim     Nachchromieren    nach       gelbolive    umschlagen. Im Chromdruck auf  Baumwolle erzeugt er olive Töne.  



       Beispiel:     10,7 Teile     8-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 80     %iger    Natronlauge in 150 Teilen  Wasser heiss gelöst, mit 10 Teilen Soda ver  setzt, abgekühlt und mit der aus 11,7 Teilen       4-Nitro-2-amino-l-phenol-6-sulfosäure    herge-    stellten     Diazoverbindung    versetzt. Nach er  folgter Kupplung wird der Farbstoff     ausge-          salzen,    filtriert und getrocknet.



  Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-nitro-2-amino-1-phenol-6-sulfonic acid is combined with aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a reddish-brown powder that dissolves in water with a yellow-red color and in sulfuric acid with a yellow color. It dyes wool from an acid bath in burgundy tones, which turn to yellow olive when chromium plating. In the chrome print on cotton it creates olive tones.



       Example: 10.7 parts of 8-aminonaphthalene-1,8-dicarboxylic anhydride are dissolved in 150 parts of hot water using 10 parts of 80% strength sodium hydroxide solution, 10 parts of soda are added, the mixture is cooled and the 11.7 parts are added 4-nitro-2-amino-1-phenol-6-sulfonic acid produced diazo compound added. After coupling has taken place, the dye is salted out, filtered and dried.

PATENT CLAIM: Process for the production of a new dye, characterized in that diazotized 4-nitro-2-amino-1-phenol-6-sulfonic acid is combined with 8-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a reddish-brown powder that dissolves in water with a yellow-red color and in sulfuric acid with a yellow color. He dyes wool from acid baths in burgundy tones, which turn to yellow olive when they are chromed. In the chrome print on cotton it creates olive tones.
