Description
Verfahren zur Herstellung einer fluoreszierenden Monotriazolverhindung. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung einer fluoreszieren den Monotriazolverbindung. Das Verfahren ist dadurch gekennzeichnet, dass man 2-(4"'- Amino-stilbyl-4")-(naphtho-1',2' : 4,5)-1,2,3- triazol-6' 2",2'-trisulfonsäure diazotiert und die Diazogruppe durch Chlor ersetzt.
Die erhaltene neue Verbindung, die 2-(4"- Chlor -stilbyl-4") - (naphtho-1'2' : 4,5) -1,2,3 triazol-6'2",2"'-trisulfonsäure, stellt. in Form ihres Natriumsalzes eine gelblich gefärbte Substanz dar. Sie soll als Aufhellungsmittel Verwendung finden.
<I>Beispiel:</I> 60,2 Teile 2-(4"'-Amino-stilbyl-4")-(naph- t.ho-1',2' :4,5)-1,2,3-triazol-6',2",2"'-trisulfon- säure werden in 600 Teilen Wasser als Na triumsalz neutral gelöst, eine wässrige Lösung von 6,9 Teilen Natriumnitrit zugegeben und bei einer Temperatur von 10-15 mit 25 Tei len konz. Salzsäure indirekt diazotiert.. Man rührt noch etwa 1 Stunde und lässt dann die Suspension der Diazoverbindung langsam zu einer,
aus 20 Teilen kristallisiertem Kupfer sulfat hergestellten, Kupferchlorürlösung bei einer Temperatur von 70-90 fliessen. Nach beendeter Umsetzung, kenntlich am Verschwin- den der Dia.zoreaktion, lässt man erkalten, fällt durch Zugabe von Kochsalz das Reaktions produkt aus, filtriert es ab und reinigt die er haltene Verbindung durch Umlösen in Gegen wart von Natriumhydrosulfit und Tierkohle.
Man erhält das Natriumsalz der 2-(4"'-Chlor- stilbyl-4") - (na.phtho-1'2' : 4,5)-1,2,3-triazol- 6'2",2"'-trisulfonsäure als gelblich gefärbtes Pulver, das den damit. behandelten Cellulose- fasern eine reine blaustichige Weisstönung ver leiht.
Process for the preparation of a fluorescent monotriazole compound. The present patent is a process for the preparation of a fluorescent monotriazole compound. The process is characterized in that 2- (4 "'- Amino-stilbyl-4") - (naphtho-1', 2 ': 4.5) -1,2,3-triazole-6' 2 ", 2'-trisulfonic acid is diazotized and the diazo group is replaced by chlorine.
The new compound obtained, the 2- (4 "- chloro-stilbyl-4") - (naphtho-1'2 ': 4.5) -1,2,3 triazole-6'2 ", 2"' - trisulfonic acid , represents. in the form of its sodium salt is a yellowish colored substance. It is said to be used as a lightening agent.
<I> Example: </I> 60.2 parts 2- (4 "'- Amino-stilbyl-4") - (naph- t.ho-1', 2 ': 4.5) -1.2, 3-triazole-6 ', 2 ", 2"' - trisulfonic acid are dissolved in 600 parts of water as a neutral sodium salt, an aqueous solution of 6.9 parts of sodium nitrite is added and 25 parts are added at a temperature of 10-15 conc. Hydrochloric acid indirectly diazotized .. The mixture is stirred for about 1 hour and then the suspension of the diazo compound is slowly
made from 20 parts of crystallized copper sulfate, copper chloride solution at a temperature of 70-90 flow. When the reaction is complete, indicated by the disappearance of the dia.zo reaction, the mixture is allowed to cool, the reaction product is precipitated by adding sodium chloride, filtered off and the compound obtained is purified by dissolving in the presence of sodium hydrosulphite and animal charcoal.
The sodium salt of 2- (4 "'- chlorostilbyl-4") - (na.phtho-1'2': 4,5) -1,2,3-triazole-6'2 ", 2" is obtained '-trisulfonic acid as a yellowish colored powder, which contains the. treated cellulose fibers are given a pure bluish white tint.
