Description
Verfahren zur Herstellung eines neuen metallhaltigen Azofarbstoffes. Es wurde gefunden, dass man einen neuen, metallhaltigen Azofarbstoff erhält, wenn wan den Farbstoff aus dianotiertem 5-Nitro-2 amiiio-l-phenol und 2-p-Tolylamino-5-oxy- naphthalin-7-sulfosäure zunächst mit einem Sechstel der zur vollständigen Metallisierung notwendigen Menge eines kupferabgebenden Mittels behandelt und hierauf bis zur Ab sättigung der metallisierbaren Gruppen mit chromabgebenden Mitteln weiter behandelt.
Der neue Farbstoff ist trocken ein bron- zierendes Pulver, welches sich in Wasser, Soda- oder Laugelösung blau- und in kon zentrierter Schwefelsäure blaurot löst. Baum wolle wird aus neutralem oder sodaalkali- schem Glaubersalzbad in blauen Tönen ge färbt.
<I>Beispiel:</I> Der aus 15,4 Teilen dianotiertem 5-Nitro- 2-amino-l-phenol und 31,5 Teilen 2-p-Tolyl- amino-5 - oxynaphthalin - 7 - sulfosäure herge stellte Farbstoff wird in 750 Teilen heissem Wasser gelöst und bei Siedetemperatur mit 4,18 Teilen kristallisiertem Kupfersulfat in Form einer konzentrierten Lösung versetzt.
Man erwärmt weiterhin zum Kochen unter gutem Rühren und - setzt dann nach einer Viertelstunde 15,6 Teile Crs0s als 5,2 o/oige Fluorchromlösung zu und erhitzt noch 36 Stunden am Rückflusskühler. Die ursprüng lich blaurote Lösung hat nach dieser Zeit in Violettblau umgeschlagen. Durch Zugabe von 200 Teilen Kochsalz kann man den Farb stoff quantitativ abscheiden.
Process for the production of a new metal-containing azo dye. It has been found that a new, metal-containing azo dye is obtained if the dye from dianotated 5-nitro-2 amiiio-1-phenol and 2-p-tolylamino-5-oxynaphthalene-7-sulfonic acid is initially mixed with one sixth of the Treated the amount of a copper-releasing agent necessary for complete metallization and then further treated with chromium-releasing agents until the metallizable groups are saturated.
The new dye is a dry bronzing powder that dissolves blue in water, soda or alkali solution and bluish red in concentrated sulfuric acid. Cotton is dyed in blue tones from a neutral or soda-alkaline Glauber's salt bath.
<I> Example: </I> The dye produced from 15.4 parts of dianotized 5-nitro-2-amino-1-phenol and 31.5 parts of 2-p-tolylamino-5-oxynaphthalene-7-sulfonic acid is dissolved in 750 parts of hot water, and 4.18 parts of crystallized copper sulfate in the form of a concentrated solution are added at the boiling point.
The mixture is heated further to the boil with thorough stirring and, after a quarter of an hour, 15.6 parts of CrsOs as 5.2% fluorochromium solution are added and the mixture is heated for a further 36 hours on the reflux condenser. The originally blue-red solution has turned violet-blue after this time. The dye can be separated quantitatively by adding 200 parts of table salt.
