  Verfahren zur Herstellung eines sauren!  Farbstoffes der     Antbrachinonreihe.       Das vorliegende Patent betrifft. ein Verfah  ren zur Herstellung eines neuen sauren Farb  stoffes der     Anthrachinonreihe    und ist dadurch  gekennzeichnet, dass man     1-amino-4-brom-          anthrachinon-2-sulfonsaures    Natrium mit     3-          (2'-Chlor-benzoyl)-amino-anilin    kondensiert.  



  Im folgenden Beispiel bedeuten Teile  Gewichtsteile.    <I>Beispiel:</I>  20,2 Teile     1-amino-4-brom-anthrachinon-2-          sulfonsaures    Natrium, 18,5 Teile     3-(2'-Chlor-          benzoyl)-amino-anilin,        7,5Teile        Natriumbikar-          bonat,    0,8 Teile     Kupferchlorür,    80 Teile     Iso-          propanol    und 160 Teile Wasser werden unter  Rühren während 2 Stunden auf 80  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  Lichtechtheit, sehr guter Wasch- und Schweiss  echtheit und guter     Walkechtheit.  



  Method of making an acidic! Antbrachinone series dye. 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- (2'-chloro-benzoyl) -amino-aniline.



  In the following example, parts mean parts by weight. <I> Example: </I> 20.2 parts of 1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium, 18.5 parts of 3- (2'-chlorobenzoyl) -amino-aniline, 7.5 parts Sodium bicarbonate, 0.8 part of copper chloride, 80 parts of isopropanol and 160 parts of water are heated to 80 for 2 hours with 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.
