Description
Verfahren zur Herstellung eines neuen chromhaltigen Azofarbstoffes. Es wurde gefunden, dass man einen neuen, wertvollen ehromhaltigen Azofarb- =toff erhält, wenn man den Farbstoff aus rliazotiertem 5-Nitro-2-amino-l-phenol und 2 - Acetylamino - 5 - oxyn.aphtalin - 7 - sulf osäure mit chromabgebenden Mitteln behandelt.
Der neue chromhaltige Farbstoff stellt trok- ken ein dunkelblaues Pulver dar, welches sich in Wasser mit blaugrauer und in ver dünnter Sodalösung mit rotstichig grauer Farbe löst. Der Farbstoff färbt Wolle aus sehwefelsaurem Bade in reinen blaugrauen, alkali- und wa.lkechten Tönen an. Baum wolle wird aus neutralem Bade ebenfalls in echten blaugrauen Tönen gefärbt.
<I>Beispiel:</I> 4,46 Gewichtsteile .des Farbstoffes aus diazotiertem 5-Nitro-2-amino-l-phenol und 2 -Acetylamino - 5 -oxynaphtalin - 7 - sulfosäure werden in 400 Teilen Wasser gelöst und mit einer 1,52 Gewichtsteilen Cr20.- entsprechen den Menge Fluorchrom 24 Stunden zum Sie- den erhitzt; die gebildete Chromverbindung wird hierauf mit Kochsalz abgeschieden, ausgewaschen und bei mässiger Temperatur getrocknet.
Process for the production of a new chromium-containing azo dye. It has been found that a new, valuable Ehrom-containing azo dye is obtained if the dye is made from rliazotized 5-nitro-2-amino-1-phenol and 2 - acetylamino - 5 - oxyn.aphthalene - 7 - sulfonic acid treated chromium-releasing agents.
The new chromium-containing dye is a dry, dark blue powder that dissolves in water with a blue-gray color and in diluted soda solution with a reddish gray color. The dye stains wool from a sulfuric acid bath in pure blue-gray, alkaline and water-resistant shades. Cotton from neutral bath is also dyed in real blue-gray tones.
<I> Example: </I> 4.46 parts by weight of the dye from diazotized 5-nitro-2-amino-1-phenol and 2-acetylamino-5-oxynaphthalene-7-sulfonic acid are dissolved in 400 parts of water and treated with a 1.52 parts by weight of Cr20.- correspond to the amount of fluorochrome heated to boiling for 24 hours; the chromium compound formed is then deposited with common salt, washed out and dried at a moderate temperature.
