Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthraehinonreihe.       Gegenstand dieses     Zusatzpatentes    ist ein  Verfahren zur Darstellung eines sauren     Chro-          mierungsfarbstoffes    der     Anthrachinonreihe,     welches dadurch gekennzeichnet ist, dass  man     1-amino-4-bromanthrachinon-2-sulfosau-          res    Natrium mit     3-Amino-4'-oxybenzophenon-          3'-carbonGä@ure    kondensiert.

      <I>Beispiel:</I>       !2i5    Gewichtsteile     3-Amino-4'-oxybenzo-          phenon-3'-carbonsäure    werden zusammen mit  26 Gewichtsteilen     1-Amino-4-bromanthra-          chinon-2-sulfosäure    in Form ihrer Natrium  salze bei<B>70'</B> C in 50 Teilen Wasser in  Gegenwart von 10 Gewichtsteilen wasser  freiem     Natriumcarbonat,        1,0    Gewichtsteilen       Natriumbicarbonat    und 1     Gewichtsteil        Kup-          ferchlorür    so lange unter Rühren erhitzt, bis  die     Farbstoffbildung    beendet ist.

   Das Re  aktionsgemisch wird nach dem Erkalten ab  gesaugt -und mit 5 %     iger    Kochsalzlösung ge  waschen. Nach eventueller weiterer Reini  gung wird ein Produkt erhalten, welches  Wolle aus saurer     Flotte    in blauen     Tönen       färbt, die     durch        Nachchromierung    in ihren  Echtheitseigenschaften wesentlich verbessert  werden.



  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 anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinone-2-sulfo-acid is sodium with 3-amino-4'-oxybenzophenone-3'- carbonGä @ ure condensed.

      <I> Example: </I>! 2i5 parts by weight of 3-amino-4'-oxybenzo-phenone-3'-carboxylic acid are used together with 26 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid in the form of its sodium salts at 70 ° C in 50 parts of water in the presence of 10 parts by weight of anhydrous sodium carbonate, 1.0 part by weight of sodium bicarbonate and 1 part by weight of copper chloride heated with stirring until the dye formation has ended.

   After cooling, the reaction mixture is sucked off and washed with 5% saline solution. After any further cleaning, a product is obtained which dyes wool from acidic liquor in blue tones, the fastness properties of which are significantly improved by subsequent chrome plating.
