Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthrachinonreihe.            Gegenstand        dieses        Zusatzpatentes        isst    -ein  Verfahren zur Darstellung     eines    sauren     Chro-          mierungsfarbstoffes    der     Anthrachmonreihe,     welches dadurch gekennzeichnet ist,

       dass'    man       1-amino        -4-#bro#manthraehinon-        2-sulfosaursss          Natrium    mit     2'-Aminobenzyl-4-oxy-3@-methyl-          5-carboxyphenylsulfon        kondensiert.       <I>Beispiel:

  </I>       2i6        Gewichtsteile    1-amino-4-bromanthra-         chinon-2,sulfosaures        Natrium,    45     Gewichts-          teile        2'-Aminobenzyl-4-oxy-3-methyl-5-oarbo-          xyphenylsulfon    der folgenden     Formel:

       
EMI0001.0028     
    21     Gewichtsteile    Soda     calc.,    1,5 Gewichts  teile     Kupferchlorür        werden    in 450 Gewichts  teilen     Wasser    bis zur     Beendigung    der Um  setzung auf 90   C     erwärmt.    Nach der Isolie  rung     und.        Reinigung    erhält man einen Farb  stoff, welcher Wolle     in        rotstichig    blauen    Tönen färbt.

   Beim     Nachchro#mieren    der  sauren Färbung erhält man ein     Marineblau     von     ausgezeichneten        Echtheitseigenschaften.  



  Process for the preparation of an acidic chromating dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of an acidic chromating dye of the anthrachmon series, which is characterized by

       that 1-amino -4- # bro # manthraehinon- 2-sulfosaursss sodium is condensed with 2'-aminobenzyl-4-oxy-3 @ -methyl-5-carboxyphenyl sulfone. <I> example:

  </I> 2i6 parts by weight of 1-amino-4-bromoanthraquinone-2, sodium sulphate, 45 parts by weight of 2'-aminobenzyl-4-oxy-3-methyl-5-oxyphenylsulphone of the following formula:

       
EMI0001.0028
    21 parts by weight of soda calc., 1.5 parts by weight of copper chloride are heated in 450 parts by weight of water to 90 C until the conversion is complete. After isolation and. After cleaning, you get a dye that dyes wool in reddish blue tones.

   When the acidic dyeing is re-chromated, a navy blue with excellent fastness properties is obtained.
