Description
Verfahren zur Herstellung eines lebhaften sauren Walkfarbstoffes der Anthrachinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines lebhaften ,sau- ren Walkfarbstoffes der Anthrachinonreihe. welches dadurch gekennzeichnet ist, dass man auf 1 - Amino - 4-(2',4',6'-trimethy 1-anilido)- anthrachinon-2,
5-disulfonsäure Brom einwir- ken lässt.
Beispiel: 5,6 Teile 1 - amino - 4-(2',4',6'-trimethyl- anilido)-anthraehinon-2,5--disulfonsaures Na trium werden bei Raumtemperatur unter Rüh ren durch Eintragen in 3,0 Teile Schwefel säuremonohydrat gelöst. Hierauf lässt man 1,8 Teile Brom zutropfen, rührt über Nacht. bei 20 bis 3i0 , erhöht gegebenenfalls die Temperatur noch während 3 Stunden auf 60".
Den bromierten Farbstoff arbeitet man auf übliche Weise auf, sei es durch Giessen der Schwefeleäurelösung in Eis und Wasser oder durch fraktionierte Fällung des sauren schwe felsauren Sailzes aus der Schwefelsäure'läsuno mittels, Zusatz von wenig Wasser.
Der Farbstoff wird in rotstickig blauen Nädelehen gewonnen, die sich in Wasser mit leuchtend grünstickig blauer Farbe leicht lö sen. Die Farbe der Lösung in konzentrierter Schwefelsäure ist schmutzig rotstickig blau; beim Zusatz von wenig Paraformaldebyd seh'lägt sie nach leuchtend rotstickig blau um. Der Farbstoff färbt tierische Fasern, wie Wolle, Seide usw., sowie künstliche Fasern, z. B. Nylon, in leuchtend. rotstickig blauen Tönen von ausgezeichneten Echtheitseigen schaften.
Der neue Farbstoff besitzt die Formel:
EMI0001.0044
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 fulled milled dye of the anthraquinone series. which is characterized in that 1 - amino - 4- (2 ', 4', 6'-trimethy 1-anilido) - anthraquinone-2,
5-disulphonic acid bromine to act.
Example: 5.6 parts of 1-amino-4- (2 ', 4', 6'-trimethyl-anilido) -anthraehinone-2,5-disulfonic acid sodium are added at room temperature with stirring by adding 3.0 parts Sulfur acid monohydrate dissolved. 1.8 parts of bromine are then added dropwise and the mixture is stirred overnight. at 20 to 30, the temperature may be increased to 60 "for a further 3 hours.
The brominated dye is worked up in the usual way, be it by pouring the sulfuric acid solution into ice and water or by fractional precipitation of the acid sulfuric acid salt from the sulfuric acid solution by adding a little water.
The dye is obtained in red-tinged blue needles, which dissolve easily in water with a bright green-tinged blue color. The color of the solution in concentrated sulfuric acid is dirty red-blue; with the addition of a little paraformaldehyde it turns into a bright red-tinged blue. The dye dyes animal fibers such as wool, silk, etc., as well as artificial fibers, e.g. B. Nylon, in luminous. red-embroidered blue tones with excellent authenticity properties.
The new dye has the formula:
