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-stilby1-4")-(na.phtho-1',2' : 4,5) -1,2,3- triazol 2",2"'-disulfonsäure dianotiert und die Diazogruppe durch Wasserstoff ersetzt.
Die erhaltene neue Verbindung, die 2-(Stil- byl-4")-(naphtho-1',2' :4,5)-1,2,3-triazol-2",2"'- clisulfonsäure, stellt in Form ihres Natrium salzes ein schwach gelbstiehiges Pulver dar. Sie soll als Aufhellungsmittel Verwendung finden.
Beispiel: Die Lösung des Dinatriumsalzes von 52,2 Teilen 2-(4"'-Amino-stilbyl-4")-(naphtho-1',2' 4,5)-7.,2,3-triazol-2",2"'-disulfonsäure und 6,9 Teilen Natriumnitrit in 600 Teilen Wasser wird bei einer Temperatur von 10-15 mit 25 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 Rüekfluss 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 Natriumhydrosulfit und Tierkohle, filtriert heiss und fällt die 2- (Stilbyl-4")-(naphtho-1',2' : 4,5)-1,2,3-triazol- 2",2"'-disulfon:säure als Natriumsalz durch Zu gabe -von Kochsalz aus. Das Produkt ist ein schwach gelbstichiges Pulver; es stellt ein wertvolles Aufhellungsmittel 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-stilby1-4") - (na.phtho-1', 2 ': 4.5) -1,2,3-triazole 2 ", 2 "'-disulfonic acid is dianotized and the diazo group is replaced by hydrogen.
The new compound obtained, 2- (stilbyl-4 ") - (naphtho-1 ', 2': 4,5) -1,2,3-triazol-2", 2 "'-clisulfonic acid, represents in In the form of its sodium salt, it is a slightly yellow powder. It is said to be used as a whitening agent.
Example: The solution of the disodium salt of 52.2 parts of 2- (4 "'- Amino-stilbyl-4") - (naphtho-1', 2 '4,5) -7., 2,3-triazol-2 " , 2 "'- disulfonic acid and 6.9 parts of sodium nitrite in 600 parts of water is concentrated at a temperature of 10-15 with 25 parts. Hydrochloric acid indirectly dianotized. The mixture is allowed to stir for about 1 hour and the diazo compound is precipitated by adding sodium chloride.
The well sucked 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 off and the residue is dissolved with sodium hydroxide solution in the case of an alkaline phenolphthalein reaction in hot water.
B. by adding sodium hydrosulfite and animal charcoal, filtered hot and falls the 2- (stilbyl-4 ") - (naphtho-1 ', 2': 4,5) -1,2,3-triazole- 2", 2 " '-disulfonic: acid as the sodium salt by adding -table salt. The product is a slightly yellowish powder; it is a valuable lightening agent for cellulose fibers, wool, soap powder and laundry aids.
