Description
Verfahren zur Herstellung eines neuen chromhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen, wertvollen chromhaltigen Azofarbstoff erhält, wenn man den Polyazofarbstoff aus 2 Mol dianotiertem 5-Nitro-2-amino-l-pheriol und 1 Mol 2,1'-Azonaphthalin-5,5'-dioxy - 2' - amino - 7,7'-disulfosäure mit chromabgebenden Mitteln behandelt.
Der neue chrombaltige Farbstoff ist trocken ein dunkles Pulver, welches sich in Wasser mit rötlich blauschwarzer, in ver dünnten Alkalien mit blauer und in konzen trierter Schwefelsäure mit grünschwarzer Farbe löst. Baumwolle und Viskose werden aus neutralem Glaubersalzbad in graugrünen Tönen gut egal angefärbt.
Beispiel: 54 Teile des in Gegenwart voii Essig säure kombinierten Monoazofarbstoffes aus dianotierter 2-Amino-5-oxyriaphthalin-7-sulfo- säure und 2-Amino-5-oxynaphthaliri-7-sulfo- säure werden in 500 Teilen Wasser gelöst und mit 50 Teilen Soda versetzt. Darauf kuppelt man mit der Diazoverbindung aus 31 Teilen 5-Nitro-2-amino-l-phenol und salzt den Farbstoff nach beendeter Kupplung aus.
Er wird in 4000 Teilen Wasser gelöst und zusammen mit der Fluorchromlösung aus 30 Teilen Cr203 20-30 Stunden am Rückfluss- kühler erwärmt. Durch Kochsalz wird die Chromverbindung abgeschieden.
Process for the production of a new chromium-containing dye. It has been found that a new, valuable chromium-containing azo dye is obtained if the polyazo dye is obtained from 2 moles of dianotized 5-nitro-2-amino-1-pheriol and 1 mole of 2,1'-azonaphthalene-5,5'-dioxy - 2 '- amino - 7,7'-disulfonic acid treated with chromium donating agents.
The new chromium-containing dye is a dry, dark powder which dissolves in water with a reddish blue-black color, in dilute alkalis with blue and in concentrated sulfuric acid with a greenish-black color. Cotton and viscose are dyed in a neutral Glauber's salt bath in gray-green tones.
Example: 54 parts of the monoazo dye combined in the presence of acetic acid from dianotized 2-amino-5-oxyriaphthalene-7-sulfonic acid and 2-amino-5-oxynaphthalene-7-sulfonic acid are dissolved in 500 parts of water and mixed with 50 Share soda added. It is then coupled with the diazo compound from 31 parts of 5-nitro-2-amino-1-phenol and the dye is salted out after the coupling has ended.
It is dissolved in 4000 parts of water and heated together with the fluorochrome solution of 30 parts of Cr203 for 20-30 hours on the reflux condenser. The chromium compound is deposited by means of table salt.
