Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 263286. Verfahren zur Herstellung eines sauren Farbstoffes der Anthraebinonreihe. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines neuen sauren Farbstoffes der Anthrachinonreihe und ist dadurch gekennzeichnet, dass man 1-amino-4- brom-anthrachinon-2-sulfonsauresNatriummit 3-(4'-Chlorbenzoyl)-amino-anilin kondensiert.
Irn folgenden Beispiel bedeuten Teile Gewichtsteile.
Beispiel: 20,2 Teile 1-amino-4-brom-anthrachinon-2- sulfonsaures Natrium,<B>18,5</B> Teile 3-(4'-Chlor- benzoyl)-amino-anilin, 10 Teile Natriumbikar- bonat, 0,3 Teile Kupferpulver, 0,3 Teile Kup- ferchlorür, 40 Teile Äthanol und 120 Teile Wasser werden unter Rühren während 6 Stun den auf 70 erhitzt.
Die blau gewordene Kondensationsmasse wird auf übliche Weise aufgearbeitet und lie fert nach dem Trocknen ein blaues Farbstoff pulver, das sich in warmem Wasser klar blau löst. Die Farbe der Lösung in konzentrierter Schwefelsäure ist hell blaugrün, beim Zusatz von wenig Paraformaldehyd tritt ein Um schlag nach tief grasgrün ein.
Der neue Farbstoff färbt Wolle, Seide und andere tierische Fasern sowie künstliche Fasern, wie z. B. Nylon, in schönen blauen Tönen an. Die Färbungen sind von guter Liehtechtheit, sehr guter Wasch- und Schweiss- eehtheit und guter Walkechtheit.
<B> Additional patent </B> to main patent no. 263286. Process for the production of an acidic dye of the anthraebinone series. The present patent relates to a process for the production of a new acidic dye of the anthraquinone series and is characterized in that 1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium is condensed with 3- (4'-chlorobenzoyl) -amino-aniline.
In the following example, parts mean parts by weight.
Example: 20.2 parts of 1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium, <B> 18.5 </B> parts of 3- (4'-chlorobenzoyl) -amino-aniline, 10 parts of sodium bicar Carbonate, 0.3 part of copper powder, 0.3 part of copper chloride, 40 parts of ethanol and 120 parts of water are 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, delivers a blue dye powder that dissolves in warm water to give a clear blue color. The color of the solution in concentrated sulfuric acid is light blue-green; when a little paraformaldehyde is added, it changes to deep grass-green.
The new dye dyes wool, silk and other animal fibers as well as artificial fibers such as B. Nylon, in beautiful blue tones. The dyeings are of good lightfastness, very good fastness to washing and perspiration and good fastness to flexing.
