  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:
EMI0001.0044
