  Verfahren zur Darstellung eines neuen     Anthrachinonfarbstoffes.       Das vorliegende Patent betrifft ein Ver  fahren zur     Darstellung    eines neuen     Anthra-          chinonfarbstoffes    und ist dadurch gekenn  zeichnet, dass man     1-amino-4-bromanthra-          5        chinon-2-sulfosaures    Natrium mit     3-Amino-6-          chlor-acetanilid    kondensiert.  



  Der neue     Farbstoff    besitzt die Formel  
EMI0001.0011     
    3 Er löst sich mit blauer Farbe in Wasser und  zieht auf Wolle in     grünstichig    blauen Tönen  von guten Echtheitseigenschaften. Er besitzt  ein     gutes        Egalisierungsvermögen.       <I>Beispiel:

  </I>    20     Gewichtsteile        1-amino-4-bromanthTa-          chinon-2-sulfosaures        Natrium    werden 150     Ge-          wichtsteilen    Wasser und 50     Gewichtsteilen     Alkohol mit 15     Gewichtsteilen        3-Amino-6-          chlor-acetanilid,    14 Gewichtsteilen     Natrium-          bicarbonat    und 0,8 Gewichtsteilen Kupfer  zirka 16     Stunden    bei 70   gerührt. Nach be  endeter     Kondensation    wird der Alkohol ab  getrieben.

   Der Farbstoff wird     abfiltriert    und  mit verdünnter     Kochsalzlösung    gewaschen  und getrocknet.    Der Farbstoff besitzt die Formel "  
EMI0001.0031     
      Er löst sich in     Wasser    mit blauer Farbe und  zieht auf Wolle     in        grünstichig    blauen Tönen  von     guten        Echtheitseigenschaften.    Er besitzt  ein gutes     Egalisiervermögen.  



  Process for the preparation of a new anthraquinone dye. The present patent relates to a process for the preparation of a new anthraquinone dye and is characterized in that 1-amino-4-bromoanthra-5-quinone-2-sulfonic acid sodium is condensed with 3-amino-6-chloroacetanilide.



  The new dye has the formula
EMI0001.0011
    3 It dissolves in water with a blue color and pulls onto wool in greenish blue tones with good fastness properties. He has a good ability to equalize. <I> example:

  </I> 20 parts by weight of 1-amino-4-bromoanthtaquinone-2-sulfonic acid sodium are 150 parts by weight of water and 50 parts by weight of alcohol with 15 parts by weight of 3-amino-6-chloroacetanilide, 14 parts by weight of sodium bicarbonate and 0 , 8 parts by weight of copper stirred at 70 for about 16 hours. After the condensation has ended, the alcohol is driven off.

   The dye is filtered off, washed with dilute sodium chloride solution and dried. The dye has the formula "
EMI0001.0031
      It dissolves in water with a blue color and pulls onto wool in greenish blue tones with good fastness properties. He has a good leveling ability.
