Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man dianotierte 6-Nitro- 2-amino-l-phenol-4-sulfosäure mit 3-Amino- naphthalin-1,8-dikarbonsäurevereinigt 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 Schwe felsäure mit rotbrauner Farbe.
Er färbt Wolle aus saurem Bade in grünen Tönen von vor züglichen Echtheitseigenschaften und gibt im Baumwolldruck, vorzugsweise in Gegenwart von Chrombeizen, echte, grüne Färbungen. <I>Beispiel:</I> 10,7 Teile 3-Aminonaphthaliri-1,8-dikar- borisäureanhydrid werden mit Hilfe von 10 Teilen 30 %iger Natronlauge in 160 Teilen Wasser heiss gelöst, mit 10 Teilen Soda ver setzt, abgekühlt und mit der aus 11,7 Teilen 6-Nitro-2-ainino-l-phenol-4-sulfosäure herge stellten Diazoverbindung versetzt.
Nach er folgter Kupplung wird der Farbstoff ausge- salzen, filtriert und getrocknet, 47,6 Teile des so erhaltenen Azofarbstoffes werden in 950 Teilen Wasser kochend ge löst, mit einer Ohromformiatlösung entspre chend 22,6 Teilen Or20s versetzt und längere Zeit am Rückflusskühler gekocht. Hierauf wird die Chromverbindung durch Aussalzen ge wonnen.
Process for the production of a new dye. It has been found that a new dye is obtained if dianotated 6-nitro-2-amino-1-phenol-4-sulfonic acid is combined with 3-amino-naphthalene-1,8-dicarboxylic acid and the azo dye thus obtained is combined with chromium-releasing agents treated. The new dye is a blackish powder and dissolves in water with green, in concentrated sulfuric acid with red-brown color.
It dyes wool from acid baths in green shades with excellent fastness properties and gives real green dyeings in cotton printing, preferably in the presence of chrome stains. <I> Example: </I> 10.7 parts of 3-aminonaphthalen-1,8-dicarboric anhydride are dissolved in 160 parts of hot water using 10 parts of 30% strength sodium hydroxide solution, 10 parts of soda are added, the mixture is cooled and with the diazo compound produced from 11.7 parts of 6-nitro-2-ainino-1-phenol-4-sulfonic acid.
After coupling, the dyestuff is salted out, filtered and dried, 47.6 parts of the azo dyestuff obtained in this way are dissolved in 950 parts of boiling water, an odor formate solution corresponding to 22.6 parts of Or20s is added and the mixture is refluxed for a long time. The chromium compound is then obtained by salting out.
