Description
Verfahren zur Herstellung eines neuen chrombaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen, chromhaltige. Farbstoff herstellen kann, wenn man den Azofarbstoff, welcher durch Vereinigen der Diazoverbindung der 1-Amino-2-oxynaphtalin-4-sulfosäure mit dem 1- (3'- Sulfamido) -phenyl-3-methyl-5- pyrazolon erhältlich ist, mit Chromformiat in der Wärme behandelt.
Der neue chrom- haltige Farbstoff bildet feine, bronzierende Kristalle; er löst sich in Wasser, unter Zu satz von Soda oder von Natronlauge, mit roter Farbe und färbt aus saurem Bade Wolle sehr gleichmässig und echt reinrosa. <I>Beispiel:
</I> 525 Teile des Farbstoffes aus der Diazoverbindung der' 1-Amino-2-oxynaphta- lin-4-sulfosäure und 1-(3'-Sulfamido)-phenyl- 3-methyl-5-pyrazolon werden in der zwanzig fachen Menge Wasser kochend gelöst, mit einer Chromformiatmenge, entsprechend 228 Teilen Cr203, versetzt und längere Zeit am Rückflusskühler gekocht. Hierauf -lässt man abkühlen und filtriert die kristallisch ab geschiedene Chromverbindung.
Process for the production of a new chromium-containing dye. It was found that a new, chromium-containing. Dye can be produced if the azo dye, which is obtainable by combining the diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid with 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone, is obtained with Chromium formate treated in the heat.
The new chromium-containing dye forms fine, bronzing crystals; it dissolves in water, with the addition of soda or caustic soda, with a red color and turns acidic bath wool very evenly and really pure pink. <I> example:
</I> 525 parts of the dye from the diazo compound of '1-amino-2-oxynaphthalen-4-sulfonic acid and 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone are twenty-fold Amount of water dissolved at the boil, mixed with an amount of chromium formate, corresponding to 228 parts of Cr203, and boiled for a long time on the reflux condenser. This is then allowed to cool and the crystalline chromium compound which has separated out is filtered off.
