Description
Verfahren zur Herstellung einer fluoreszierenden Monotriazolverbindung. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer fluoreszie renden hlonotriazolverbindung. Das Verfah ren ist dadurch gekennzeichnet, dass man di anotierte 4-Amino-stilben-2-sulfonsäure mit 2-Amino-naphthalin-3-carbonsäure zum o- Aminoazofarbstoff kuppelt und diesen zur 2-Stilbyl-(4")-(3'-carboxy-naphtho-1',2' : 4,5) 1,2,3-triazol-2"-sulfonsäure oxydiert.
Das Natritunsalz der erhaltenen neuen Ver bindung ist ein schwach gelbstichiges Pulver. Sie soll als Aufhellungsmittel Verwendung finden.
Beispiel: Eine Lösung von 27,5 Teilen 4 - Amino- stilben - 2 - sulfonsäure, 4,1 Teilen Natrium hydroxyd und 6,9 Teilen Natriumnitrit in 200 Teilen Wasser wird bei 8 bis 10 mit 25 Teilen Salzsäure indirekt dianotiert. Die Suspension der Diazoverbindimg wird mit einer Lösung von 18,7 Teilen 2-Amino-naphthalin-3-carbon- säure, 4,1 Teilen Natriumhydroxyd und 25 Teilen kristallisiertem Natriumacetat in 300 Teilen Wasser bei einer Temperatur von 10 bis 12 gekuppelt.
Man isoliert den o-Amino- azofarbstoff, löst ihn in 600 Teilen warmem Pyridin und setzt 12 Teile Natriiunhydroxyd in 20 Teilen Wasser und einige Tropfen Tür- kischrotöl n -t.
Bei einer Temperatur von 65 bis 75 tropft man innerhalb einer halben Stunde 152 Teile einer 17 % igen Natrium- hypochloritlösung zu und rührt bis ztun voll- ständigen Verschwinden des Farbstoffes. Man lässt erkalten und trennt die wässerige Schicht ab.
Das Pyridin wird unter Zusatz von 100 Teilen Wasser und 10 Teilen Natriumhydroxyd mit Wasserdampf abdestilliert; dabei scheidet sich die 2-Stilbyl-naphthotriazolverbindung im Rückstand als hellgelbe Substanz aus. Man filtriert von der noch warmen Mutterlauge ab, wäscht mit wenig warmem Wasser nach und trocknet bei 50 bis 60 .
Das Natriumsalz der 2-Stilbyl-(4")-(3'-carboxy-naphtho-1',2', : 4,5)- 1,2,3-triazol-2"-stdfonsäure wird als schwach gelbstichiges Pulver erhalten. Auf Cellulose- fasern erzeugt die Verbindung eine blau stichige Weisstönung von ausgezeichneter Chlorechtheit und guter Licht- und Nassecht- heit. Das Produkt-verleiht auch Seifenpulvern und synthetischen Waschmitteln im Tageslicht ein weisseres Aussehen.
Process for the preparation of a fluorescent monotriazole compound. The present patent is a process for the preparation of a fluoreszie-generating hlonotriazole compound. The process is characterized in that di anotated 4-amino-stilbene-2-sulfonic acid is coupled with 2-amino-naphthalene-3-carboxylic acid to form the o-aminoazo dye and this to form 2-stilbyl (4 ") - (3 ' -carboxy-naphtho-1 ', 2': 4,5) 1,2,3-triazol-2 "-sulfonic acid oxidized.
The sodium salt of the new compound obtained is a slightly yellowish powder. It should be used as a lightening agent.
Example: A solution of 27.5 parts of 4 - amino stilbene - 2 - sulfonic acid, 4.1 parts of sodium hydroxide and 6.9 parts of sodium nitrite in 200 parts of water is indirectly dianotated at 8 to 10 with 25 parts of hydrochloric acid. The suspension of the diazo compound is coupled with a solution of 18.7 parts of 2-amino-naphthalene-3-carboxylic acid, 4.1 parts of sodium hydroxide and 25 parts of crystallized sodium acetate in 300 parts of water at a temperature of 10-12.
The o-amino azo dye is isolated, dissolved in 600 parts of warm pyridine and 12 parts of sodium hydroxide are added to 20 parts of water and a few drops of Turkish red oil.
At a temperature of 65 to 75, 152 parts of a 17% strength sodium hypochlorite solution are added dropwise within half an hour and the mixture is stirred until the dye has completely disappeared. It is allowed to cool and the aqueous layer is separated off.
The pyridine is distilled off with steam with the addition of 100 parts of water and 10 parts of sodium hydroxide; the 2-stilbyl-naphthotriazole compound separates out in the residue as a pale yellow substance. The still warm mother liquor is filtered off, washed with a little warm water and dried at 50 to 60.
The sodium salt of 2-stilbyl- (4 ") - (3'-carboxy-naphtho-1 ', 2',: 4,5) - 1,2,3-triazole-2" -stdfonic acid is obtained as a slightly yellowish powder . On cellulose fibers, the compound creates a blue-tinged white tint with excellent chlorine fastness and good light and wet fastness. The product also gives soap powders and synthetic detergents a whiter appearance in daylight.
