Description
Verfahren zur Herstellung eines neuen Farbstoffes der Anthrachinonreihe. Es wurde gefunden, dass man einen neuen Farbstoff der Anthrachinonreihe erhält, wenn man auf 1 Hol Cyanurehlorid 1 Hol 1- Amino-4-(4'-amino-diphenyl)-amino-anthra.- chinon-2-sulfosäure und 2 Hol Methylamin derart einwirken lässt,
dass ein Halogenatom des Cyanurchlorides durch 1 Hol des Di- aminoanthrachinonderivates und die zwei andern Halogenatome durch je 1 Hol Methyl- amin ausgetauscht werden.
Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit blauer Farbe löst und Baumwolle, Viskose, Wolle oder Seide in grünstichigblauen Tönen von vor züglicher Lichtechtheit färbt. <I>Beispiel:</I> 18,5 Teile Cyanurchlorid werden in 800 Teilen Wasser fein suspendiert. Zu dieser Suspension giesst man eine neutrale Lösung von 48,5 Teilen 1-Amino-4-(4'-amino-diphe- nyl)-amino-anthrachinon-2-sulfonsäure in 120O Teilen Wasser.
Man rührt bei 2,0' <B>8</B> -bis 4 .Sunden und giesst allmählieh 50 Teile 10%ige Nat#3,rbanatlösung dazu, so dass die Reaktion immer neutral bleibt. Dann gibt man 40 Teile einer 40 % igen Nethyl- aininlösung dazu. Man erhöht nun die Tem peratur allmählich bis auf 90 , macht durch Zugabe von Natriumkarbonat alkalisch und salzt den gebildeten Farbstoff aus..
Process for the production of a new dye of the anthraquinone series. It has been found that a new dye of the anthraquinone series is obtained if one pole of cyanuric chloride 1 pole of 1-amino-4- (4'-amino-diphenyl) -amino-anthra.-quinone-2-sulfonic acid and 2 poles of methylamine are used let it take effect
that one halogen atom of the cyanuric chloride is exchanged for 1 hol of the di-aminoanthraquinone derivative and the two other halogen atoms with 1 hol of methylamine each.
The new dye forms a dark powder that dissolves in water with a blue color and dyes cotton, viscose, wool or silk in greenish-blue tones that are extremely lightfast. <I> Example: </I> 18.5 parts of cyanuric chloride are finely suspended in 800 parts of water. A neutral solution of 48.5 parts of 1-amino-4- (4'-aminodiphenyl) -amino-anthraquinone-2-sulfonic acid in 120O parts of water is poured into this suspension.
The mixture is stirred for 2.0 '8 to 4 hours and 50 parts of 10% sodium bicarbonate solution are gradually poured in, so that the reaction always remains neutral. Then 40 parts of a 40% strength ethyl ainine solution are added. The temperature is now gradually increased to 90, made alkaline by adding sodium carbonate and salting out the dye formed.
