Description
<B>Verfahren zur Herstellung einer</B> fluoreszierenden Benztriazolverhindung. (xegeristand vorliegenden Patentes ist ein Verfahren zur Herstellung einer fluoreszieren den Benztriazolverbindung. Das Verfahren ist dadurch gekennzeichnet, dass man diazotierte 4-Ainino-stilben-2-sulfonsäure mit 4-iMethyl- l,3-diamino-benzol kuppelt, den erhaltenen c-Aminoazofarbstoff zur 1,2,
3-Tria.zolverbin- dung oxydiert und die Aminogruppe acety- liert.
Die erhaltene neue 6-1Iethyl.5-a.cetamino- 2-(stilbyl-4')-1,2,3-benztriazol-2'-sulfonsäure stellt in Form ihres Natriumsalzes eine gelb stichige Substanz dar, die, auf Cellulosefasern ausgefärbt, eine reine, blaustichige Weiss tönung ergibt.
<I>Beispiel:</I> In 200 Teilen Wasser werden mit 4,1 Tei len Natriumhydroxyd <B>27,5</B> Teile 4-Amino-stil- ben 2-sulfonsäure gelöst und bei 8-10 mit. 25 Teilen konzentrierter Salzsäure indirekt diazotiert. Die Diazosuspension wird bei 10 bis 12 mit einer Lösung von 1.2,2 Teilen 4-lle- tiiyl-1,3-diamino-benzol und 10 Teilen konzen trierter Salzsäure in 200 Teilen Wasser ver einigt und hierauf langsam eine Lösung von 40 Teilen kristallisiertem Natriumacetat in <B>100</B> Teilen Wasser zugegeben.
Nach beendeter Kupplung wird der o-. niino-azofarbstoff durch Zugabe von Kochsalz vollständig aus gefällt, abfiltriert und mit. verdünnter Koch salzlösung gewaschen. Der feuchte Farbstoff wird unter Zusatz von 20 Teilen 25o/oigem Ammoniak in heissem Wasser bei 90-95 klar gelöst und hierauf eine ;Mischung aus 60 Tei- len kristallisiertem Kupfersulfat in 240 Tei len Wasser mit 120 Teilen 25o/oigem Ammo niak zugegeben.
Man hält bis zur vollständi gen Oxydation des o-Amino-azofarbstoffes zur Benztriazolverbindung auf einer Temperatur von 92-95 , lässt erkalten und fällt das Pro clukt durch Zugabe von Kochsalz vollstän dig aus. Das Rohprodukt wird in Gegenwart.
von überschüssigem Natriumsulfid in heissem Wasser oder heissem, verdünntem Alkohol gelöst, das entstandene Kupfersulfid abfil- triert, die überschüssige Alkalisulfidverbin- dung durch Salzsäure zersetzt und das Pro dukt durch. I?mlösen aus Wasser oder ver dünntem Alkohol weiter gereinigt.
Das Na triumsalz der 6-Methyl-5-amino-2-(stilbyl-4')- 1.,2,3-benzti-iazol-2'-sulfonsäure wird als gelb stichige Substanz erhalten. Zur Acetylieriuig werden 40,6 Teile dieser Säure in 200 Teilen Essigsäureanhydrid während einiger Stunden unter Rückfluss zum Sieden erhitzt.
Nach dem Verschwinden der diazotierbaren Amino- gruppe entfernt man die Hauptmenge des überschüssigen Essigsäureanhydrids und der entstandenen Essigsäure, trägt den Rückstand in. Wasser ein, filtriert nach der Zersetzung des restlichen Essigsäureanhydrids ab und löst das Produkt unter Zugabe von Soda bis zur schwach brillantalkalischen Reaktion aus Wasser oder verdünntem Alkohol unter Zu gabe von Tierkohle und Natriumhydrosulfit um.
lIan erhält das Natriumsalz der 6-lZethyl- 5-aeetamino ?-(stilbyl-4')-1,2,3-benztriazol-2'- sulfonsäure als gelbstichige Substanz. Diese Verbindung stellt ein wertvolles Aufhellungs- mittel für Cellulosefasern, für Seifenpulver und synthetische Waschmittel dar unverleilit den damit. behandelten Cellulosefasern eine reine blaustichige Weisstönung.
<B> Process for the production </B> of a fluorescent benzotriazole compound. (xegeristand present patent is a process for the production of a fluorescent benzotriazole compound. The process is characterized in that diazotized 4-amino-stilbene-2-sulfonic acid is coupled with 4-iMethyl- 1,3-diamino-benzene, the resulting c- Aminoazo dye for 1,2,
3-Tria.zolverbin- dung oxidized and the amino group acetylated.
The new 6-1Iethyl.5-a.cetamino- 2- (stilbyl-4 ') -1,2,3-benzotriazole-2'-sulfonic acid obtained is, in the form of its sodium salt, a yellowish-tinged substance that stains on cellulose fibers , gives a pure, bluish white tint.
<I> Example: </I> In 200 parts of water with 4.1 parts of sodium hydroxide <B> 27.5 </B> parts of 4-amino-stilbene 2-sulfonic acid are dissolved and at 8-10 parts with. 25 parts of concentrated hydrochloric acid indirectly diazotized. The diazo suspension is combined at 10 to 12 with a solution of 1.2.2 parts of 4-lle- tiiyl-1,3-diamino-benzene and 10 parts of concentrated hydrochloric acid in 200 parts of water and then slowly a solution of 40 parts of crystallized sodium acetate added in <B> 100 </B> parts of water.
After the coupling is complete, the o-. Niino-azo dye completely precipitated by adding sodium chloride, filtered off and mixed with. Washed diluted saline solution. The moist dye is dissolved in hot water at 90-95 with the addition of 20 parts of 25% ammonia, and a mixture of 60 parts of crystallized copper sulfate in 240 parts of water with 120 parts of 25% ammonia is added.
It is kept at a temperature of 92-95 until the o-amino-azo dye is completely oxidized to the benzotriazole compound, allowed to cool and the product is completely precipitated by adding sodium chloride. The crude product is in the presence.
Dissolve excess sodium sulphide in hot water or hot, diluted alcohol, filter off the copper sulphide formed, decompose the excess alkali sulphide compound with hydrochloric acid and the product through. I dissolve in water or diluted alcohol further purified.
The sodium salt of 6-methyl-5-amino-2- (stilbyl-4 ') - 1., 2,3-benzti-iazole-2'-sulfonic acid is obtained as a yellowish substance. For acetylation, 40.6 parts of this acid in 200 parts of acetic anhydride are heated to boiling under reflux for a few hours.
After the diazotizable amino group has disappeared, most of the excess acetic anhydride and the acetic acid formed are removed, the residue is poured into water, the remaining acetic anhydride is filtered off after decomposition and the product is dissolved with the addition of soda until a slightly brilliantly alkaline reaction Water or diluted alcohol with the addition of animal charcoal and sodium hydrosulphite.
The sodium salt of 6-lZethyl-5-aeetamino? - (stilbyl-4 ') - 1,2,3-benzotriazole-2'-sulfonic acid is obtained as a yellowish substance. This compound is a valuable lightening agent for cellulose fibers, for soap powder and synthetic detergents and is unleashed with it. treated cellulose fibers a pure bluish white tint.
