Description
Verfahren zur Herstellung eines neuen metallhaltigen Polyazofarbstoffes. Es wurde gefunden, da13 man einen neuen metallhaltigen Polyazofarbstoff erhält, wenn man den; Mou.oazo@farbsto:
ff aus 1 Mol. 5,5'-Di- oxy-2,2'-dinaphthylamin-7,7'-disulfosäure und 1 Mol. diazotiertemf 4-Chlor-2-amino-l-phenol mit kupferabgebenden Mitteln behandelt,
die er haltene Komplexkupferverbindung weiter mit 1 Mol. diazotiertem 4-Chlor-2-amino-l-phenol kuppelt und die entstandene Kupferverbin dung des Dsazofarbstoffes bis zur voll ständigen Sättigung der metallisierbaren Gruppen mit kupferabgebenden Mitteln wei terbehandelt.
Der neue Farbstoff löst sich in Wasser und in 10 %iger Sodalösung oder Natron lauge mit rotvioletter und in konzentrierter Schwefelsäure mit schwärzlichblauer Farbe. Er färbt Baumwolle aus neutralem oder alka lischem Färbebad violett. <I>Beispiel:</I> 46,1 Teile 5,5'-Dioxy-2,2'-dinaphthyl- amin-7,7'-disulfosäure werden in<B>709</B> Teilen Wasser zusammen mit 30 Teilen Soda gelöst und mit der Diazolösung aus 14;3 Teilen 4- Chlor-2-amino-l-phenol kombiniert.
Der durch Aussalzen wie üblich aufgearbeitete rote Farbstoff wird in 6000 Teilen Wasser heiss gelöst und mit 25 Teilen. Kupfersulfat in Form einer konzentrierten] Lösung versetzt und eine Viertelstunde unter Rühren auf dem Wasserbad erwärmt. Der Farbstoff nimmt dabei eine violette Nuance an und wird durch Kochsalz quantitativ abgeschieden.
In Was ser und konzentrierter,S'chwefelsäure löst er sich violett, in Sodalösung oder verdünnter Ätzalkalilauge blaurot. Er färbt Baumwolle aus glaubersalzhaltigem Färbebad rotviolett .an.
Der neue Farbstoff wird nun in 1000 Tei len einer 5 %igen Sodalösung gelöst resp. suspendiert und weiterhin mit der Diazo- lösung aus 14,3 Teilen 4-Chlor-2-amino-l- phenol gekuppelt.
Die wie üblich isolierte Monokupferverbindung wird nun in 6000 Teilen Wasser heiss gelöst, mit einer kon- zentrierten Lösung aus 25 Teilen Kupfer sulfat versetzt und eine Stunde auf dem Wasserbad erwärmt. Die gebildete Kupfer verbindung wird hierauf wie üblich isoliert und getrocknet. Sie färbt Baumwolle aus neutralem oder alkalischem Färbebad violett.
Process for the preparation of a new metal-containing polyazo dye. It has been found that a new metal-containing polyazo dye is obtained if the; Mou.oazo@farbsto:
ff treated from 1 mol. 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid and 1 mol. diazotized 4-chloro-2-amino-1-phenol with copper-releasing agents,
he obtained complex copper compound further coupled with 1 mol. Diazotized 4-chloro-2-amino-l-phenol and the resulting copper compound of the disazo dye is further treated with copper-donating agents until the metallizable groups are completely saturated.
The new dye dissolves in water and in 10% soda solution or caustic soda with red-violet and in concentrated sulfuric acid with a blackish-blue color. It dyes cotton from a neutral or alkaline dye bath purple. <I> Example: </I> 46.1 parts of 5,5'-dioxy-2,2'-dinaphthylamine-7,7'-disulfonic acid are added to <B> 709 </B> parts of water together with 30 Parts of soda dissolved and combined with the diazo solution of 14; 3 parts of 4-chloro-2-amino-1-phenol.
The red dye, worked up by salting out as usual, is dissolved in 6000 parts of hot water and then added to 25 parts. Copper sulfate in the form of a concentrated] solution and heated for a quarter of an hour while stirring on the water bath. The dye takes on a violet shade and is quantitatively deposited by table salt.
In water and concentrated sulfuric acid it dissolves violet, in soda solution or dilute caustic lye it dissolves blue-red. He dyes cotton from a dyebath containing Glauber's salt red-violet.
The new dye is now dissolved in 1000 parts of a 5% soda solution, respectively. suspended and further coupled with the diazo solution of 14.3 parts of 4-chloro-2-amino-1-phenol.
The monocopper compound isolated as usual is then dissolved in 6000 parts of hot water, mixed with a concentrated solution of 25 parts of copper sulfate and heated for one hour on a water bath. The copper compound formed is then isolated and dried as usual. It dyes cotton from a neutral or alkaline dye bath purple.
