Description
Verfahren zur Herstellung einer fluoreszierenden Monotriazolverbindung. 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-5',2",2"'-trisulfonsäure dianotiert und die Diazogruppe durch Wasserstoff ersetzt.
Die erhaltene neue Verbindung, die 2-(Stil- byl-4")-(napht.ho-1',2' : 4,5)-1,2,3-triazol-5',2", 2"'-trisulfonsäure, stellt in Form ihres Na triumsalzes ein schwach gelbstichiges Pulver dar. Sie soll als Aufhellungsmittel Verwen dung finden.
<I>Beispiel:</I> Die Lösung des Trinatriumsalzes von 60,2 Teilen 2-(4"'-Amino-stilbyl-4")-(naphtho-1',2': 4,5)-1,2,3-triazol-5',2",2"'-trisulfonsäure und 6,9 Teilen Natriumnitrit in 500 Teilen Wasser wird bei einer Temperatur von 10-15 mit ?5 Teilen konz. Salzsäure indirekt dianotiert. Man lässt etwa 1 Stunde ausrühren und fällt die Diazoverbindung durch Zugabe von Koch salz aus.
Die gut abgenutschte Diazoverbin- dung wird nun portionenweise in 1000 Teile siedenden Alkohol eingetragen und während mehreren Stunden, bis zum Verschwinden der Diazoreaktion, unter Rückfloss erhitzt. Man lässt auf Zimmertemperatur erkalten, filtriert ab und löst den Rückstand mit Natronlauge bei phenolphthaleinalkalischer Reaktion in heissem. Wasser, klärt die erhaltene Lösung z.
B. durch Zugabe von Natriurnhydrosulfit und Tierkohle, filtriert heiss tusd fällt die 2- (Stilbyl-4")-(naphtho-1',2' : 4,5)-1,2,3-triazol- 5',2",2"'-trisulfonsäure als Natriumsalz durch Zugabe von Kochsalz aus. Das Produkt ist ein schwach gelbstichiges Pulver. Es stellt ein wertvolles Aufhelhungsmittel für Cellulose- fasern, Wolle, Seifenpulver und Waschhilfs mittel dar.
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-5', 2 ", 2 "'- trisulfonic acid is dianotized and the diazo group is replaced by hydrogen.
The new compound obtained, the 2- (stilbyl-4 ") - (napht.ho-1 ', 2': 4,5) -1,2,3-triazole-5 ', 2", 2 "' -trisulfonic acid, in the form of its sodium salt, is a slightly yellowish powder. It is said to be used as a lightening agent.
<I> Example: </I> The solution of the trisodium salt of 60.2 parts of 2- (4 "'- Amino-stilbyl-4") - (naphtho-1', 2 ': 4.5) -1.2 , 3-triazol-5 ', 2 ", 2"' - trisulfonic acid and 6.9 parts of sodium nitrite in 500 parts of water are concentrated at a temperature of 10-15 with 5 parts. Hydrochloric acid indirectly dianotized. The mixture is stirred for about 1 hour and the diazo compound is precipitated by adding sodium chloride.
The well sucked off diazo compound is then introduced in portions into 1000 parts of boiling alcohol and refluxed for several hours until the diazo reaction disappears. It is allowed to cool to room temperature, filtered and the residue is dissolved in hot sodium hydroxide solution with an alkaline phenolphthalein reaction. Water, the resulting solution clarifies e.g.
B. by adding sodium hydrosulfite and animal charcoal, filtered hot tusd falls the 2- (stilbyl-4 ") - (naphtho-1 ', 2': 4.5) -1,2,3-triazole- 5 ', 2" 2 "'- trisulfonic acid as the sodium salt by adding common salt. The product is a slightly yellowish powder. It is a valuable lightening agent for cellulose fibers, wool, soap powder and laundry aids.
