Description

  

  Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn . man     diazotierte        6-          Nitro-2-amino-l-phenol-4-sulfosäure    mit     3-          Aminonaphthalin-1,8-dikarbonsäure    vereinigt.  Der neue Farbstoff bildet ein schwarzes  Pulver, das sich in Wasser mit     violettroter,     in Schwefelsäure mit grüngelber Farbe löst.  Er färbt Wolle aus saurem Bade in     violett-          braunen    Tönen, welche beim     Nachchromieren     nach olive umschlagen. Im Chromdruck auf  Baumwolle erzeugt er grüne Töne.

           Beispiel:       10,7 Teile     3-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 30     %iger    Natronlauge in 150 Teilen  Wasser heiss gelöst, mit 10 Teilen Soda ver  setzt, abgekühlt und mit der aus 11,7 Teilen       6-Nitro-2-amino-l-phenol-4-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 when. diazotized 6-nitro-2-amino-1-phenol-4-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a black powder that dissolves in water with a purple-red color and in sulfuric acid with a green-yellow color. He dyes wool from an acid bath in violet-brown tones, which turn to olive when they are chromed. In the chrome print on cotton it creates green tones.

           Example: 10.7 parts of 3-aminonaphthalene-1,8-dicarboxylic 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 the 11.7 parts are added 6-nitro-2-amino-1-phenol-4-sulfonic acid produced diazo compound was added. After coupling has taken place, the dye is salted out, filtered and dried.
