Description
Verfahren zur Herstellung eines sauren Farbstoffes der Anthrachinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines sauren Farb stoffes der Anthrachinonreihe und ist dadurch gekennzeichnet, dass man 1-amino-4-broman- thrachinon-2-sulfonsaures Kalium mit p-Ben- zoylmethylaminoanil.in kondensiert.
Im folgenden Beispiel bedeuten Teile Ge- wichtsteile.
<I>Beispiel:</I> 8,4 Teile 1-amino - 4 - bromanthrachinon-2- sulfonsaures Kalium, 9 Teile p-Benzoyl-me- thyl-aminoanilin, 10 Teile Natriumbicarbonat, 0,1 Teil Kupferbronze und 0,3 Teil Kupfer- chlorür werden in 50 Teilen Alkohol und 250 Teilen Wasser aufgeschlämmt und die blasse unter Rühren während 6 Stunden auf 70 erhitzt.
Die blau gewordene Kondensationsmasse wird auf übliche Weise aufgearbeitet und lie fert nach dem Trocknen ein blaues Farbst.off- pulver, das sich in Wasser mit lebhaft blauer Farbe löst. Die Lösung in konzentrierter Schwefelsäure ist blaugrün, beim Zusatz von wenig Paraformaldehyd tritt ein Umschlag nach grasgrün ein.
Der neue Farbstoff färbt Wolle, Seide und andere tierische Fasern sowie künstliche Fa sern, wie z. B. Nylon, in schönen blauen Tönen an. Die Färbungen sind von sehr guter Licht- echtheit, sehr guter Wasch- und Schweissecht heit und guter Walkechtheit.
Process for the preparation of an acidic dye of the anthraquinone series. The present patent relates to a process for the production of an acidic dye of the anthraquinone series and is characterized in that 1-amino-4-bromanthrachinone-2-sulfonic acid potassium is condensed with p-benzoylmethylaminoanil.in.
In the following example, parts mean parts by weight.
<I> Example: </I> 8.4 parts of 1-amino - 4 - bromoanthraquinone-2-sulfonic acid potassium, 9 parts of p-benzoyl-methyl-aminoaniline, 10 parts of sodium bicarbonate, 0.1 part of copper bronze and 0, 3 parts of copper chloride are suspended in 50 parts of alcohol and 250 parts of water and the pale is heated to 70 for 6 hours while stirring.
The condensation mass, which has turned blue, is worked up in the usual way and, after drying, produces a blue dye powder which dissolves in water with a vivid blue color. The solution in concentrated sulfuric acid is blue-green; if a little paraformaldehyde is added, it changes to grass-green.
The new dye dyes wool, silk and other animal fibers and artificial fibers, such as. B. Nylon, in beautiful blue tones. The dyeings have very good light fastness, very good wash and perspiration fastness and good flexing fastness.
