Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man dianotierte 4-Nitro- 2-amino-l-phenol-6-sulfosäure mit 3-Amino- naphthalin-1,8-dikarbonsäure vereinigt und den so erhaltenen Azofarbstoff mit chromabgeben den Mitteln behandelt. Der neue Farbstoff stellt ein schwärzliches Pulver dar und löst sich in Wasser mit grüner, in konzentrierter Schwefelsäure mit gelbbrauner Farbe.
Er färbt Wolle aus saurem Bade in grünen Tönen von vorzüglichen Echtheitseigenschaften und gibt im Baumwolldruck, vorzugsweise in Gegenwart von Chrombeizen, echte, grüne Färbungen.
Beispiel: 10,7 Teile 3-Aminonaphthalin-1,8-dikar- bonsäureanhydrid werden mit Hilfe von 10 Teilen 30 o%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.
47,6 Teile des so erhaltenen Azofarb- stoffes werden in 950 Teilen Wasser lochend gelöst, mit einer Ohromfluoridlösung entspre chend 22,6 Teilen Or20s versetzt und längere Zeit in Gegenwart von Glaspulver am R,ück- flusskühler gekocht. Die gebildete Chromver bindung wird abfiltriert, mit Wasser ge waschen, in lauwarmer, verdünnter, wässeriger Natronlauge gelöst und nach Neutralstellen der Lösung mit Essigsäure in üblicher Weise abgeschieden.
Process for the production of a new dye. It has been found that a new dye is obtained if dianotated 4-nitro-2-amino-1-phenol-6-sulfonic acid is combined with 3-amino-naphthalene-1,8-dicarboxylic acid and the azo dye thus obtained is given off with chromium Means treated. The new dye is a blackish powder and dissolves in water with green, in concentrated sulfuric acid with yellow-brown color.
It dyes wool from an acid bath in green shades with excellent fastness properties and gives real, green dyeings 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 with the aid of 10 parts of 30% strength sodium hydroxide solution, 10 parts of soda are added, the mixture is cooled and the solution from 11.7 Parts of 4-nitro-2-amino-1-phenol-6-sulfonic acid herge provided diazo compound added. After coupling has taken place, the dye is salted out, filtered and dried.
47.6 parts of the azo dye thus obtained are dissolved with holes in 950 parts of water, an ohmic fluoride solution corresponding to 22.6 parts of Or20s is added and the mixture is boiled for a long time in the presence of glass powder on a reflux condenser. The chromium compound formed is filtered off, washed with water, dissolved in lukewarm, dilute, aqueous sodium hydroxide solution and, after the solution has been rendered neutral with acetic acid, deposited in the usual way.
