Description
Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man das 6-Nitro-2- amino-1.-oxybenzol - 4 - sulfamid diazotiert, hierauf mit 1 - (3'-Sulfamido)-phenyl-5-py- razolon-3-karbonsäure kuppelt und den so erhaltenen Farbstoff mit Fluorchrom be handelt.
Der neue Farbstoff bildet ein orangebraunes Pulver, löst sich in Wasser und in 10 %iger Natronlauge mit oranger, in konzentrierter Schwefelsäure mit gelber Farbe und färbt Wolle aus saurem Bade in orangen Tönen mit vorzüglichen Eigen- scb aften. Beispiel:
?3,3 Teile 6-Nitro-2-amino-l-oxybenzol- 4-sulfamid werden in üblicher Weise mit 6,9 Teilen Natriumnitrit diazotiert. Die Diazo- lösung lässt man in eine eiskalte Lösung von 28,3 Teilen 1 - (3'-Sulfamido)-phenyl-5-py- razolon-3-larbonsäure und 30 Teilen Soda in ?50 Teilen Wasser unter Rühren einfliessen. Die Reaktionsmasse wird nach vollendeter Kupplung auf 50 angewärmt und der Farb stoff mit Kochsalz ausgesalzen und in üb licher Weise isoliert.
50 Teile des so erhaltenen Farbstoffes werden in 1500 Teilen Wasser kochend ge löst. Man versetzt hierauf mit einer Fluor chromlösung entsprechend<B>15,2</B> Teilen Cr203, kocht unter Zusatz von Glaspulver längere Zeit am Rückflusskühler und scheidet die Chromverbindung durch Aussalzen oder Eindampfen und Aussalzen aus.
Process for the production of a new dye. It has been found that a new dye is obtained if the 6-nitro-2-amino-1-oxybenzene-4-sulfamide is diazotized, then with 1 - (3'-sulfamido) -phenyl-5-pyrazolone -3-carboxylic acid is coupled and the dye thus obtained is treated with fluorochrome.
The new dye forms an orange-brown powder, dissolves in water and in 10% sodium hydroxide solution with orange, in concentrated sulfuric acid with yellow color and dyes wool from acid baths in orange shades with excellent properties. Example:
3.3 parts of 6-nitro-2-amino-1-oxybenzene-4-sulfamide are diazotized in the usual way with 6.9 parts of sodium nitrite. The diazo solution is allowed to flow into an ice-cold solution of 28.3 parts of 1- (3'-sulfamido) -phenyl-5-pyrazolone-3-carbonic acid and 30 parts of soda in 50 parts of water with stirring. After coupling is complete, the reaction mass is heated to 50 and the dye is salted out with sodium chloride and isolated in the usual way.
50 parts of the dye thus obtained are dissolved at the boil in 1500 parts of water. A fluorochromium solution corresponding to <B> 15.2 </B> parts of Cr203 is then added, the mixture is boiled for a long time in a reflux condenser with the addition of glass powder and the chromium compound is separated out by salting out or evaporation and salting out.
