Description

  

  Verfahren zur Herstellung eines     Wollfarbstoffes    der     Anthrachinonreihe.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines Wollfarb  stoffes der     Anthrachinonreihe,    dadurch ge  kennzeichnet, dass man     1-amino-4-(m-amino-          phenyl)-aniino-anthrachinon-2-sulfosaLires    Na  trium mit einem     Ohloracetylierungsmittel     kondensiert.  



  Der neue     Farbstoff    färbt Wolle in vollen  klaren,     rotstichig    blauen Tönen von ausge  zeichneten Echtheitseigenschaften, wie Walk  und Lichtechtheit an. Das     Egalisierungsver-          mögen    des Farbstoffes ist sehr gut.  



  <I>Beispiel:</I>       1.6,5    kg     1-ainino-4-(in-aminopheiiyl)-amino-          anthrachinon-2-sulfosaures    Natrium werden  in 3000 Liter Wasser gelöst, die Lösung  abgekühlt und bei stets schwach alkalischer  Reaktion mit 12 kg     Chloracetylchlorid    ver-    setzt. Nachdem die     Farbstoffbildung    beendet  ist, wird der     Farbstoff    durch     Aussalzen    abge  schieden.



  Process for the production of a wool dye of the anthraquinone series. The present patent relates to a process for the production of a wool dye of the anthraquinone series, characterized in that 1-amino-4- (m-aminophenyl) -aniino-anthraquinone-2-sulfosaLires sodium is condensed with a chloroacetylating agent.



  The new dye dyes wool in full, clear, reddish-tinged blue tones with excellent fastness properties such as fulling and lightfastness. The leveling power of the dye is very good.



  <I> Example: </I> 1.6.5 kg of 1-ainino-4- (in-aminopheiiyl) -amino-anthraquinone-2-sulfonic acid sodium are dissolved in 3000 liters of water, the solution is cooled and with an always weakly alkaline reaction with 12 kg of chloroacetyl chloride were added. After the dye formation has ended, the dye is deposited by salting out.
