Description
Verfahren zur Herstellung eines lebhaften sauren Walkfarbstoffes der Anthrachinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines lebhaften sauren Walkfarbstoffes der Anthrachinonreihe und ist dadurch gekennzeichnet, dass man auf 1- Amino-4-(2',4',6'-trimethyl-anilido) - anthra- chinon - 2,6 - disulfonsäure Chlor einwirken lässt.
<I>Beispiel:</I> 5,9 Teile 1 - amino - 4-(.2,4',6:'- trimethyl- anilido)-anthrac.hinon-2"6-disulfonz,aures Ka lium werden bei Raumtemperatur unter Rüb.- ren in 50 Teilen Schwefelsäure <B>8,5%</B> gelöst.
Hierauf leitet man bei 2'0 bis 30 unter wei terhin gutem Rühren 2 Teile Chlor ein und s erhöht zum Schluss die Temperatur noch wäh rend einer Stunde auf 60 . Den chlorierten Farbstoff arbeitet man auf übliche Weise auf, sei es durch Giessen der Schwefelsäure lösung in Eis und Wasser oder durch frak tionierte Fällung .des sauren schwefelsauren Salzes aus der Schwefelsäurelösung mittels Zusatz von wenig Wasser.
Der Farbstoff wird in rotstichig blauen Nädejlehen gewonnen, .die sich in Wasser mit leuchtend blauer Farbe leicht lösen. Die Farbe der Lösung in konzentrierter Schwe felsäure ist schmutzig rotstichig blau; beim Zusatz von wenig Paraformaldehyd schlägt sie nach leuchtend rotstichig blau um. Der Farbstoff färbt tierische Fasern, wie Wolle, Seide usw., sowie künstliche Fasern, z. B.
Nylon, in leuchtend rotstichig blauen Tönen von ausgezeichneten Echtheiten, Der Farbstoff besitzt die Formel

Process for the production of a lively acidic milled dye of the anthraquinone series. The present patent relates to a process for the production of a lively acidic milled dyestuff of the anthraquinone series and is characterized in that 1-amino-4- (2 ', 4', 6'-trimethyl-anilido) - anthraquinone - 2, 6 - disulfonic acid allows chlorine to act.
<I> Example: </I> 5.9 parts of 1 - amino - 4 - (. 2,4 ', 6:' - trimethyl anilido) -anthrac.hinon-2 "6-disulfonz, acidic potassium are used in Room temperature dissolved under stirring in 50 parts of sulfuric acid <B> 8.5% </B>.
2 parts of chlorine are then passed in at 20 to 30 with continued stirring, and finally the temperature is increased to 60 for one hour. The chlorinated dye is worked up in the usual way, either by pouring the sulfuric acid solution into ice and water or by fractional precipitation of the acidic sulfuric acid salt from the sulfuric acid solution by adding a little water.
The dye is obtained in reddish-tinged blue threads which easily dissolve in water with a bright blue color. The color of the solution in concentrated sulfuric acid is dirty reddish blue; if a little paraformaldehyde is added, it changes to a bright reddish blue. The dye dyes animal fibers such as wool, silk, etc., as well as artificial fibers, e.g. B.
Nylon, in bright reddish blue tones with excellent fastness properties. The dye has the formula
