Description

  

  Verfahren zur     Ifferstellung    eines     Wollfarbstoffes    der     Anthraehinonreihe.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Wollfarb-          stoffes    der     Antbrachinonreihe,    dadurch ge  kennzeichnet, dass man     1-amino-4-(m-äthyl-          aininophenyl)    -     amino-anthrachinon-2-sulfosau-          res    Natrium mit einem     Chloracetylierungs-          mittel    kondensiert.  



  Der neue Farbstoff färbt Wolle klar und  kräftig blau.  



  <I>Beispiel:</I>  36 kg     1-amino-4-(in-äthylaminophenyl)-          ainino-arithrachinon-2-sulfosaures    Natrium  werden in 6000 Liter Wasser gelöst und  diese Lösung bei 10   mit 20 kg     Ohloracetyl-          chlorid    versetzt. Die Reaktion der Lösung    wird durch ständiges     Zutropfen    einer Soda  lösung schwach alkalisch gehalten.



  Process for the production of a wool dye of the anthraehinone series. The present patent relates to a process for the production of a wool dye of the antbrachinone series, characterized in that 1-amino-4- (m-ethyl-ainophenyl) -amino-anthraquinone-2-sulfo-acid sodium with a chloroacetylation medium condensed.



  The new dye gives wool a clear, strong blue color.



  <I> Example: </I> 36 kg of 1-amino-4- (yn-ethylaminophenyl) - ainino-arithraquinone-2-sulfonic acid sodium are dissolved in 6000 liters of water and this solution is mixed with 20 kg of chloroacetyl chloride at 10 o'clock. The reaction of the solution is kept weakly alkaline by constant dropping of a soda solution.
