  <B>Zusatzpatent</B> zum. Hauptpatent     Nr:    254809.    Verfahren zur Herstellung eines lebhaften sauren     Walkfarbstoffes     der     Anthrachinonreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Herstellung eines lebhaften  sauren     Walkfarbstoffes    der     Anthrachinon-          reihe    und ist dadurch     gekennzeichnet.    dass  man auf     1-Amino-4-(2',3',6'-triäthyl-anilido)-          anthrachinon-2,5-disulfonsäui-e    Brom einwir  ken lässt.  



  <I>Beispiel:</I>  6,0 Teile 1-     amino    - 4 - (2',3',6' -     tr        iätliyl-          anilido)-anthracliinon-2,5-disulfonsaures    Na  trium werden bei Raumtemperatur unter  Rühren in 50 Teilen Schwefelsäure 95<B>?7,</B> ge  löst. Hierauf leitet man bei 20-30  unter  weiterhin gutem Rühren 1. Teil Brom ein und  erhöht zum Schluss die Temperatur noch  während 3 Stunden auf 40". Den     bromierten     Farbstoff arbeitet man auf übliche Weise    auf, sei es durch Giessen der Schwefelsäure  in Eis und Wasser oder durch fraktionierte  Fällung des sauren schwefelsauren Salzes aus  der     Schwefelsäurelösung    mittels Zusatz von       wenig    Wasser.  



  Der Farbstoff wird in     rotstichig    blauen       Nädelchen    gewonnen, die sieh in Wasser     mit     leuchtend blauer Farbe leicht, lösen. Die  Farbe der Lösung in konzentrierter Schwefel  säure ist, schmutzig     rotstiehig    blau; bei Zu  satz von wenig     Parafornialdehyd    schlägt sie  nach leuchtend     rotstichig    blau um. Der Farb  stoff färbt tierische Fasern, wie Wolle,  Seide usw., sowie künstliche Fasern, z. B.  Nylon, in leuchtend     rotstichig    blauen Tönen  von ausgezeichneten     Eehtheiten.

  <B> Additional patent </B> for. Main patent no: 254809. 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 milled dye of the anthraquinone series and is characterized in this. that you can act on 1-amino-4- (2 ', 3', 6'-triethyl-anilido) - anthraquinone-2,5-disulfonic acid bromine.



  <I> Example: </I> 6.0 parts of 1- amino - 4 - (2 ', 3', 6 '- trietliylanilido) -anthracliinon-2,5-disulfonic acid sodium are stirred at room temperature in 50 parts of sulfuric acid 95 <B>? 7 </B> dissolved. The first part of bromine is then introduced at 20-30 with continued stirring and the temperature is finally increased to 40 "for 3 hours. The brominated dye is worked up in the usual way, be it by pouring the sulfuric acid into ice and water or by fractional precipitation of the acidic sulfuric acid salt from the sulfuric acid solution by adding a little water.



  The dye is obtained in reddish-tinged blue needles that easily dissolve in water with a bright blue color. The color of the solution in concentrated sulfuric acid is a dirty reddish blue; if a little parafornialdehyde is added, it changes to a bright reddish blue. The dye dyes animal fibers such as wool, silk, etc., as well as artificial fibers such. B. Nylon, in bright reddish blue tones of excellent integrity.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen lebhaften sauren Walkfarbstoffes der An- thrachinonreilie, dadurch gekennzeichnet, dass man auf X-Amino-4-(2',3',6'-t.riätliyl-anilido)- anthrachinoii 2,5-disulfonsäure Brom einwir ken lässt. Der neue Farbstoff besteht aus rotstichig blauen Nädelehen, die sich in Wasser finit leuchtend blauer Farbe leicht lösen.. PATENT CLAIM: A process for the production of a new, lively acidic fulled dyestuff of the anthraquinone range, characterized in that one uses on X-amino-4- (2 ', 3', 6'-t.riätliyl-anilido) - anthrachinoii 2,5-disulfonic acid Allows bromine to act. The new dye consists of reddish-tinged blue needles that easily dissolve in water, finite, bright blue color. Die Farbe der Lösung in konzentrierter Schwe felsäure ist schmutzig rotstickig blau; bei Zu satz von wenig Paraformaldehyd schlägt sie nach leuchtend rotstickig blau um. Der Farb stoff färbt tierische Fasern, wie Wolle, Seide usw., sowie künstliche Fasern, z. B. Nylon, in leuchtend rotstickig blauen Tönen von ausge zeichneten Echtheiten. Der Farbstoff besitzt die Formel EMI0002.0006 The color of the solution in concentrated sulfuric acid is dirty red-blue; if a little paraformaldehyde is added, it changes to a bright red-embroidered blue. The dye dyes animal fibers such as wool, silk, etc., as well as artificial fibers such. B. nylon, in bright red embroidered blue tones of excellent fastness properties. The dye has the formula EMI0002.0006
