Description
Verfahren zur Herstellung einer fluoreszierenden Benztriazolverbindung. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung einer fluoreszie renden Benztriazolverbindung. Das Verfahren ist dadurch gekennzeichnet, da.ss man diano tierte 4- Amino-stilben-2-sulfonsäure mit 1,3- Diamino-benzol kuppelt, den erhaltenen o- Amino-azofarbstoff zur 1,2,
3-Triazolverbin- dung oxydiert und dann die Aminogruppe acetyliert.
Die erhaltene neue 5-Acetamino-2-(stilbyl- 4')-1,2,3-benztriazol-2'-sulfonsäure stellt in Form ihres Natriumsalzes eine gelbstichige Substanz dar, die, auf Cellulosefasern aus gefärbt, eine reine, blaustichige Weisstönung ergibt.
<I>Beispiel:</I> In 200 Teilen Wasser werden mit 4,1 Tei len Natriitmhydroxyd 27,5 Teile 4-Amino-stil- ben-2-sulfonsäure gelöst und bei 8-10 mit 25 Teilen konzentrierter Salzsäure indirekt dianotiert. Die Diazosuspension wird bei 10 bis 12 mit einer Lösung von 10,8 Teilen 1,3- Diamino-benzol und 10 Teilen konzentrierter Salzsäure in 200 Teilen Wasser vereinigt und hierauf langsam eine Lösung von 40 Teilen kristallisiertem Natriumacetat in 100 Teilen Wasser zugegeben.
Nach beendeter Kupplung wird der o -@mino-azofarbstoff durch Zugabc von Kochsalz vollständig ausgefällt, abfiltriert und mit verdünnter Kochsalzlösung gewa- sehen. Der feuchte Farbstoff wird unter Zu satz von 20 Teilen 25o/oigem Ammoniak in heissem Wasser bei 90-95 klar gelöst und hierauf eine Mischung aus 60 Teilen kristalli- siertem Kupfersulfat in 240 Teilen Wasser mit 120 Teilen 25o/oigem Ammoniak zugege ben.
Man hält bis zur vollständigen Oxyda tion des o-Amiiio-azofarbstoffes zur Benztri- azolverbindung auf einer Temperatur von 92 bis 95 , lässt erkalten und fällt das Produkt durch Zugabe von Kochsalz vollständig aus. Das Rohprodukt wird in Gegenwart von über schüssigem Natriumsulfid in heissem Wasser oder heissem, verdünntem Alkohol gelöst, das entstandene Kupfersulfid abfiltriert, die über schüssige Alkalisulfidverbindung durch Salz säure zersetzt. und das Produkt durch Um lösen aus Wasser oder verdünntem Alkohol weiter gereinigt.
Das Natriumsalz der 5- Amino-2- (stilbyl-4')-1,2,3-benztriazol-2'-sulfon- säure wird als gelbgrünstichige Substanz er halten. Zur Acetylierimg werden 39,2 Teile dieser Säure in 200 Teilen Essibsäiireanhydrid während einiger Stunden unter Rückfluss zum Sieden erhitzt.
Nach dem Verschwinden der diazotierbaren Aminogruppe entfernt man die Hauptmenge des überschüssigen Essigsäure anhydrids und der entstandenen Essigsäure, trägt den Rückstand in Wasser ein, filtriert nach der Zersetzung des restlichen Essigsäure anhy drids ab und löst das Produkt unter Zu gabe von Soda bis zur schwach brillantalkali schen Reaktion aus Wasser oder verdünntem Alkohol unter Zugabe von Tierkohle und Na- triumhydrosulfit um.
Man erhält das Natrium salz der 5-Aeetamino-2-(stilbyl-4')-1,2,3-benz- triazol-2'-sulfonsäure als gelbstichige Sub stanz. Diese Verbindung stellt ein wertvolles Aufhellungsmittel für Cellulosefasern, für Seifenpulver und synthetisehe Waschmittel dar und verleiht. den damit. behandelten Cel- lulosefasern eine reine, blaustiehige Weiss tönung.
Process for producing a fluorescent benzotriazole compound. The present patent relates to a process for the preparation of a fluorescent benzotriazole compound. The process is characterized in that diano-tated 4-amino-stilbene-2-sulfonic acid is coupled with 1,3-diamino-benzene, the resulting o-amino-azo dye to 1,2,
3-triazole compound is oxidized and then the amino group is acetylated.
The new 5-acetamino-2- (stilbyl-4 ') -1,2,3-benzotriazole-2'-sulfonic acid obtained is, in the form of its sodium salt, a yellowish substance which, when dyed on cellulose fibers, has a pure, bluish white tint results.
<I> Example: </I> 27.5 parts of 4-amino-stilbene-2-sulfonic acid are dissolved in 200 parts of water with 4.1 parts of sodium hydroxide and indirectly dianotated at 8-10 with 25 parts of concentrated hydrochloric acid. The diazo suspension is combined at 10 to 12 with a solution of 10.8 parts of 1,3-diamino-benzene and 10 parts of concentrated hydrochloric acid in 200 parts of water, and a solution of 40 parts of crystallized sodium acetate in 100 parts of water is then slowly added.
After the coupling has ended, the o - @ mino-azo dye is completely precipitated by adding sodium chloride, filtered off and washed with dilute sodium chloride 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 then added.
It is maintained at a temperature of 92 to 95 until complete oxidation of the o-amino azo dye to the benzotriazole compound, allowed to cool and the product is completely precipitated by adding sodium chloride. The crude product is dissolved in hot water or hot, diluted alcohol in the presence of excess sodium sulfide, the copper sulfide formed is filtered off and the excess alkali metal sulfide compound is decomposed by hydrochloric acid. and the product is further purified by dissolving it from water or diluted alcohol.
The sodium salt of 5-amino-2- (stilbyl-4 ') -1,2,3-benzotriazole-2'-sulfonic acid is obtained as a yellow-greenish substance. For acetylation, 39.2 parts of this acid in 200 parts of acetic anhydride are refluxed 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 added to water, the remaining acetic anhydride is filtered off after decomposition and the product is dissolved with the addition of soda up to the weakly brilliant alkali Reaction from water or diluted alcohol with the addition of animal charcoal and sodium hydrosulphite.
The sodium salt of 5-ethamino-2- (stilbyl-4 ') -1,2,3-benz-triazole-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 gives. the one with it. treated cellulose fibers a pure, bluish white tint.
