Description
Verfahren zur Herstellung eines neuen ebromhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen chromhaltigen Farbstoff herstellen kann, wenn man den Azofarbstoff, welcher durch Vereinigen der Diazoverbindung der 2- Amino-l-oxy-4-chlor-5-benzolsulfosäure mit dem 1-(3'-Sulfamido)-phenyl-3-methyl-5-pyr- azolon erhältlich ist, mit Fluorchrom in der Wärme behandelt.
Der neue chromhaltige Farbstoff bildet ein braunes Pulver, er löst sich in Wasser unter Zusatz von Soda oder von Natronlauge mit oranger Farbe und färbt aus saurem Bade Wolle sehr gleich mässig und echt gelbrot. Beispiel: 512 Teile des Farbstoffes aus dar Diazo- verbindung der 2-Amino-l-o@xy-4-chlor-5-ben- zolsulfosäure und 1-(3'-Sulfamido)-phenyl- 3-methyl-5-pyrazolon werden in 6000 Teilen Wasser kochend gelöst, mit 5000 Teilen einer Fluorchromlösung, entsprechend 243 Teilen Cr203,
versetzt und längere Zeit am Rück flusskühler gekocht. Hierauf wird ein Teil der Flüssigkeit abgedampft und der Farb stoff durch Aussalzen abgeschieden.
Process for the preparation of a new ebromine-containing dye. It has been found that a new chromium-containing dye can be produced if the azo dye, which is obtained by combining the diazo compound of 2-amino-1-oxy-4-chloro-5-benzenesulfonic acid with 1- (3'-sulfamido) - phenyl-3-methyl-5-pyr-azolone is available, treated with fluorochrome in the heat.
The new chromium-containing dye forms a brown powder, it dissolves in water with the addition of soda or caustic soda with an orange color and turns acidic bath wool very evenly and really yellow-red. Example: 512 parts of the dye from the diazo compound of 2-amino-lo @ xy-4-chloro-5-benzene sulfonic acid and 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone are in 6000 parts of boiling water, with 5000 parts of a fluorochrome solution, corresponding to 243 parts of Cr203,
and boiled for a long time on the reflux condenser. Part of the liquid is then evaporated and the dye is deposited by salting out.
