Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 287563.    Verfahren     zur    Herstellung     eines    sauren     Walkfarbstoffes    der     Anthrachinonreihe.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines sauren       Wallfarbstoffes    der     Anthrachinonreihe,    wel  ches darin besteht, dass man 1-Amino-4       (4'-benzoylamino)-phenylaminoanthraehinon-          2-sulfonsällre    durch Behandeln mit einem  bromfierenden Mittel in den     dibromierten    Ab  kömmling überführt.  



       Beispiel:     53,5 Teile     1-amino-4-        (4'-benzoylamino)-          plienyiaminoanthrachinon-2-sulfonsaures    Na  trium werden in 1200 Teilen 96 %     iger    Schwe  felsäure gelöst und mit 24 Teilen Brom ver  setzt. Man rührt 48 Stunden lang bei Raum  temperatur und arbeitet den Farbstoff auf.  Er ist ein     rötlicllblaues    Pulver, das sich in  Wasser mit     rotstichig    blauer Farbe löst.

   Seine       Lösungsfarbe    in konzentrierter Schwefelsäure  ist     rotstichig    blau; beim Zusatz von     Paraform-          aldehyd    erfolgt ein Umschlag nach Grün.  



  Der neue Farbstoff färbt     urolle    und andere  tierische Fasern sowie Nylon in klaren,     rot-          stiehig    blauen Tönen von hervorragender       'Valkeehtheit    und     guter        Liehtechtheit    und be  sitzt ferner ein ausgezeichnetes     Neutra.lzieh-          vermögen.  



  <B> Additional patent </B> to main patent no. 287563. Process for the production of an acidic fulled dyestuff of the anthraquinone series. The subject of the present patent is a process for the preparation of an acidic wall dye of the anthraquinone series, wel Ches consists in that 1-amino-4 (4'-benzoylamino) -phenylaminoanthraehinone-2-sulfonsällre by treating with a brominating agent in the dibrominated from convicted.



       Example: 53.5 parts of 1-amino-4- (4'-benzoylamino) - plienyiaminoanthraquinone-2-sulfonic acid sodium are dissolved in 1200 parts of 96% sulfuric acid and 24 parts of bromine are added. The mixture is stirred for 48 hours at room temperature and the dye is worked up. It is a reddish blue powder that dissolves in water with a reddish blue color.

   Its solution color in concentrated sulfuric acid is a reddish blue; when paraformaldehyde is added, the color changes to green.



  The new dye dyes urolla and other animal fibers as well as nylon in clear, reddish-blue shades of excellent valkyfastness and good lightfastness, and also has excellent neutral properties.
