Description
Zusatzpatent zum Hauptpatent Nr. <B>135748.</B> Verfahren zur Herstellung eines Azofarbstoffes. Es wurde gefunden" dass man einen neuen inetallhaltigen Azofarbstoff erhält, wenn man 2 Mol. 2-Amino-5-oxynaphthalin-7-sulfosäure, 2 Mol. diazotierte 1-Aminoi-4-sulfo-2-benzol- i,arbgnsäure, <B>1</B> Mol. Cyanurel-i-lorid,
<B>1</B> Mol. Anilin und kupferabgebende Mittel aufein ander einwirken lässt und diese verschiedenen Operationen derart vornimmt, dass die Be handlung mit den kupferabgebenden Mitteln nicht vor der Kupplungsreaktion vorgenom men und die Kondensation mit Cyanurchlo- rid derart durchgeführt -wird, dass'die 2 Mol. 2,-Amino-5-#oxyna,pli.thalin-7-sulfos,ä,ure und das Mol. Anilin durch eine NH-Gruppe an den Tria,
zinkern gebunden werden.
Der neue Farbstoff bildet ein dunkel- i-otbraunes Pulver, löst sieh in Wasser mit --elbbrauner Farbe und erzeugt auf Baum wolle oder Kunstseiden, wie Vishos-e- oder KLipferoxydammoniahseide" gelbbraune Töne von vorzüglicher Liehteahtheit.
<I>Beispiel:</I> Man stellt in bekannter Weise das tertiäre Nondensationsprod-tikt aus<B>1</B> Igol. Cyanur- chlorid, 2 Mol. 2-Amino-5-o.xynaphthalin-7- eulio,sä,ure, und<B>1</B> Mol. Anilin dar.
64,8 Teile des obigen tertiären Konden- s#ationsprodüktes werden in<B>800</B> Teilen Was ser und<B>60</B> Teilen Natriumearbo#nat gelöst, auf<B>5 '</B> gekühlt und 43,2 Teile diazotierte 1- Amino-4-sulfa-#2i.benzoloa,rbonsä,ure einge rührt.
Nach erfolgter Kupplung heizt man auf<B>70 '</B> auf, säuert mit verdünnter Schwef el- säure an, versetzt mit überschüssiger 2,0 '/o- iger Kupfersulfatlösung und rührt eine Stunde bei<B>80</B> bis<B>90,'.</B> Die Kupferverbin dung wird nach erfolgter Isolierung mit ver dünntem überschüssigem Ammoniak in das A2mmonsalz übergefÜhrt und isoliert.
Zum gleichen Produkt gelangt man selbst- verständlich# a-uüh, wenn man die Reihenfolge der beschriebenen bezw. erwähnten Operatio nen sinngemäss ändert.
Additional patent to main patent no. <B> 135748. </B> Process for the production of an azo dye. It has been found that a new metal-containing azo dye is obtained if 2 moles of 2-amino-5-oxynaphthalene-7-sulfonic acid, 2 moles of diazotized 1-amino-4-sulfo-2-benzene-1, arbic acid, < B> 1 </B> mol. Cyanurel-i-loride,
<B> 1 </B> Mol. Aniline and copper-releasing agent can act on one another and these various operations are carried out in such a way that the treatment with the copper-releasing agents is not carried out before the coupling reaction and the condensation with cyanuric chloride is carried out in this way that 'the 2 mol. 2, -amino-5- # oxyna, pli.thalin-7-sulfos, ä, ure and the mol. aniline through an NH group on the tria,
zinc be bound.
The new dye forms a dark brown powder, dissolves in water with a yellow-brown color and produces yellow-brown tones of excellent lightness on cotton or artificial silk, such as Vishos-e or Klipferoxydammoniahseide.
<I> Example: </I> The tertiary nondensation product is established in a known manner from <B> 1 </B> Igol. Cyanuric chloride, 2 mol. 2-Amino-5-o.xynaphthalene-7-eulio, acid, ure, and <B> 1 </B> mol. Aniline.
64.8 parts of the above tertiary condensation product are dissolved in <B> 800 </B> parts of water and <B> 60 </B> parts of sodium carbonate, to <B> 5 '</B> cooled and 43.2 parts of diazotized 1-amino-4-sulfa- # 2i.benzoloa, rboxylic acid, stirred in.
After coupling is complete, the mixture is heated to 70%, acidified with dilute sulfuric acid, excess 2.0% copper sulfate solution is added and the mixture is stirred at 80% for one hour > to <B> 90, '. </B> After isolation, the copper compound is converted into the ammonium salt with diluted excess ammonia and isolated.
Of course, you get to the same product # a-uüh if you follow the order of the described or. changes mentioned operations accordingly.
