Description

  

  Verfahren Mir     Herstellung    eines     Wollfarbstoffes    der     Anthrachinonreilie.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Wollfarb-          stoffes    der     Anthrachinonreihe,    dadurch ge  kennzeichnet, dass man     1-amino-4-(p-amino-          phenyl)-aminoauthrachinon-2-sulfosaures    Na  trium mit     Chlorkohlensäureäthylester    konden  siert.  



  Der neue Farbstoff färbt Wolle aus saurem  Bade gleichmässig in     reinblauen    Tönen an.  <I>Beispiel:</I>       33,2    kg     1-amino-4-(p-aminophenyl)-amino-          anthrachinon-2-sulfosaures    Natrium werden  in     "0000    Liter Wasser gelöst bei 10-20  ,  mit 20 kg     Ghlorlkohlensäureäthylester    bei    stets schwach alkalischer Reaktion behandelt.  Der Farbstoff wird wie üblich isoliert.



  Process with the production of a wool dye of the anthraquinone line. The present patent relates to a process for the production of a wool dye of the anthraquinone series, characterized in that 1-amino-4- (p-aminophenyl) -aminoauthraquinone-2-sulfonic acid sodium is condensed with ethyl chlorocarbonate.



  The new dye dyes wool from an acid bath evenly in pure blue tones. <I> Example: </I> 33.2 kg of 1-amino-4- (p-aminophenyl) -amino-anthraquinone-2-sulfonic acid are dissolved in "0000 liters of water at 10-20, with 20 kg of carbonic acid ethyl ester always treated with a weakly alkaline reaction The dye is isolated as usual.
