Description

  

      Terfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotiertes        4-          Chlor-5-nitro-2-amino-l-phenol    mit     3-Amino-          naphtha-Iin-1,8-dikarbonsäure        vereinigt.    Der  neue Farbstoff bildet ein schwarzes Pulver,  das sich in Wasser mit     violettroter,    in Schwe  felsäure mit rotbrauner Farbe löst. Er färbt  Wolle aus saurem Bade in blauroten Tönen,  welche beim     Nachchromieren    nach grün um  schlagen. Im Chromdruck auf Baumwolle  erzeugt er graue 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 9,4 Teilen       4-Chlor-5-nitro-2-amino-l-phenol    hergestell-         ten        Diazoverbindung    versetzt. Nach erfolg  ter Kupplung wird der Farbstoff     ausgesal-          zen,    filtriert und getrocknet.



      Terfahren for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-chloro-5-nitro-2-amino-1-phenol is combined with 3-amino-naphtha-Iin-1,8-dicarboxylic acid. The new dye forms a black powder that dissolves in water with a violet-red color and in sulfuric acid with a red-brown color. It dyes wool from acid baths in blue-red tones, which turn green when they are chrome-plated. In the chrome print on cotton it creates gray 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 9.4 parts are added 4-chloro-5-nitro-2-amino-1-phenol produced diazo compound was added. After coupling has taken place, the dye is salted out, filtered and dried.
