Description

  

  Verfahren zur Herstellung eines sauren     Wollfarbstoffes    der     Anthrachinonreihe.       Gegenstand des vorliegenden     Patentes    ist  ein Verfahren zur Herstellung eines neuen,  sauren Wollfarbstoffes der     Anthrachinon-          reihe    :durch     Umsetzung    von     1-Hexahydro-          an2lido-4-bromanthrachinon-7-sulfosäure    mit       p-Aminoacetanilid.     



  Die Umsetzung kann in wässrig alkali  schem     Medium    zweckmässig in Gegenwart  eines Kupfersalzes vorgenommen werden.  Der     erhaltene    neue Farbstoff scheidet sich  beim Erkalten aus. Er     stellt    grüne Nadeln  dar, die sich in Wasser mit grüner Farbe  lösen und Wolle aus saurem Bade lebhaft  grün färben.  



  <I>Beispiel:</I>  10     Gewichtsteile        1-Hegahy        droanilido-4-          bromanthrachinon-7-sulfosäure    werden mit  10     Gewichtsteilen    p-     Aminoacc:tanilid    unter  Zugabe von 10 Gewichtsteilen Natrium  bicarbonat und 0,5     Gewichtsteilen    Kupfer  chlorür in 150 Gewichtsteilen Wasser  C Stunden auf 60 bis 80   C erhitzt. Nach  dem Erkalten wird der abgeschiedene Farb-         stoff        abgesaugt    und aus Wasser umkristalli  siert. Er stellt grüne Nadeln dar, die sich in .  Wasser mit grüner Farbe lösen und Wolle  aus saurem Bade lebhaft grün färben.



  Process for the production of an acidic wool dye of the anthraquinone series. The subject of the present patent is a process for the production of a new, acidic wool dye of the anthraquinone series: by reacting 1-hexahydroan2lido-4-bromoanthraquinone-7-sulfonic acid with p-aminoacetanilide.



  The reaction can conveniently be carried out in an aqueous alkaline medium in the presence of a copper salt. The new dye obtained separates out on cooling. It represents green needles that dissolve in water with a green color and dye wool from acid baths vividly green.



  <I> Example: </I> 10 parts by weight of 1-Hegahydroanilido-4-bromoanthraquinone-7-sulfonic acid are mixed with 10 parts by weight of p-Aminoacc: tanilide 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 Heated to 60 to 80 C for hours. After cooling, the deposited dye is suctioned off and recrystallized from water. It represents green needles that are in. Dissolve water with green color and dye wool from acidic baths vividly green.
