Description

  

      Verfahren    zur Herstellung eines sauren     Wollfarbstoffes    der     Anthraehinonreihe.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur     Herstellung    eines neuen .sau  ren     Wollfarbstoffes    der     Anthra.chinonreihe     durch     Umsetzung    von     1-Hexahydroanilido-4-          bromanthrachinon-7-sulfosäure    mit     m-Amino-          acetanilid.     



  Die Umsetzung kann     .in        -,vä.ssrio7        .a.lka.li-          schem    Medium, zweckmässig in Gegenwart  eines Kupfersalzes vorgenommen     werden.     



  Der neue Farbstoff stellt blaue Nadeln  dar, die sich in Wasser mit     grünstickig     blauer Farbe lösen und. Wolle aus saurem  Bade lebhaft     grünstickig    blau färben.    <I>Beispiel:</I>    10 Gewichtsteile     1-Hexahydroanilido-4-          bromanthrachinon-7-sulfosäure    werden mit  10 Gewichtsteilen     m-Aminoacetanilid        unter     Zugabe von 10 Gewichtsteilen Natrium  biearbonat und 0,5 Gewichtsteilen Kupfer  chlorür in 150     Gewichtsteilen    Wasser  G Stunden auf 60 bis 80   C erhitzt.

   Nach  dem Erkalten wird der abgeschiedene Farb-         stoff        abgesaugt    und aus Wasser umkristalli  siert.     .Er    stellt blaue Nadeln .dar,     :die    sich in  Wasser mit     grünstickig    blauer Farbe lösen  und Wolle aus saurem Bade. lebhaft     gTün-          stichig    blau färben.



      Process for the production of an acidic wool dye of the anthraehinone series. The subject of the present patent is a process for the production of a new .sau ren wool dye of the anthraquinone series by reacting 1-hexahydroanilido-4-bromoanthraquinone-7-sulfonic acid with m-aminoacetanilide.



  The reaction can be carried out in, vä.ssrio7 .a.lka.li- shem medium, expediently in the presence of a copper salt.



  The new dye represents blue needles that dissolve in water with a greenish blue color and. Lively dye wool from an acid bath in a greenish blue. <I> Example: </I> 10 parts by weight of 1-hexahydroanilido-4-bromoanthraquinone-7-sulfonic acid are mixed with 10 parts by weight of m-aminoacetanilide with the addition of 10 parts by weight of sodium bicarbonate and 0.5 part by weight of copper chloride in 150 parts by weight of water for G hours Heated at 60 to 80 C.

   After cooling, the deposited dye is suctioned off and recrystallized from water. It represents blue needles: which dissolve in water with a greenish blue color, and wool from an acid bath. color lively, favorable blue.
