Description

  

  Verfahren zur Darstellung eines     Farbstoffes    der     Anthrachinonreihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines Farbstoffes  der     Anthrachinonreihe,    welches dadurch ge  kennzeichnet ist, dass man     1-Bromanthrachi-          non-2-sulfochlorid    mit     Methyltaurin    konden  siert und das so erhaltene     1-Bromanthra-          chinon-2-sulfomethyltaurid    weiter mit     m-Ami-          nodimethylanilin    kondensiert.  



  <I>Beispiel:</I>  270 Gewichtsteile     1-Bromantbrachinon-2-          sulfochlorid,    110 Gewichtsteile     Methyltaurin,     80 Gewichtsteile Soda     calc.    werden in 2000  Teilen Wasser 5 Stunden bei<B>80-850</B> ge  rührt. Die erhaltene Lösung wird heiss filtriert  und erkalten gelassen, wobei sich das Na  triumsalz des     1-Bromanthrachinon-2-sulfo-          methyltaurid    ausscheidet. Man saugt ab und  wäscht mit     10o/oiger    Kochsalzlösung neutral.  



  25 Gewichtsteile des so erhaltenen     1-          Bromanthrachinon-2-sulfomethyltaurid        (Na-          Salz),    20 Gewichtsteile     m-Aminodimethyl-          anilin,    5 Gewichtsteile     calc.    Soda, 250 Ge  wichtsteile Wasser und 0,5 Gewichtsteile         Kupferchlorür    werden solange bei 40-50 o C  gerührt, bis die Kondensation beendet ist.  



  Nach Aufarbeitung des Reaktionsgemisches  erhält man einen grünen, kristallinischen  Farbstoff, der sich in Wasser mit klarer  grüner Farbe löst und auf Wolle klare gelb  atichiggrüne Farbtöne liefert.



  Process for the preparation of a dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of a dye of the anthraquinone series, which is characterized in that 1-bromoanthraquinone-2-sulfochloride is condensed with methyltaurine and the 1-bromoanthraquinone-2-sulfomethyltauride obtained in this way continues with m - Ami- nodimethylaniline condensed.



  <I> Example: </I> 270 parts by weight of 1-bromantbrachinone-2-sulfochloride, 110 parts by weight of methyl taurine, 80 parts by weight of soda calc. are stirred in 2000 parts of water at <B> 80-850 </B> for 5 hours. The resulting solution is filtered hot and allowed to cool, the sodium salt of 1-bromoanthraquinone-2-sulfomethyltauride separating out. It is suctioned off and washed neutral with 10% sodium chloride solution.



  25 parts by weight of the 1-bromoanthraquinone-2-sulfomethyl tauride (Na salt) obtained in this way, 20 parts by weight of m-aminodimethyl aniline, 5 parts by weight of calc. Soda, 250 parts by weight of water and 0.5 parts by weight of copper chloride are stirred at 40-50 o C until the condensation has ended.



  After working up the reaction mixture, a green, crystalline dye is obtained which dissolves in water with a clear green color and gives clear, yellowish green color shades on wool.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farb stoffes der Anthrachinonreihe, dadurch ge kennzeichnet, dass man 1-Bromanthrachinori- 2-sulfochlorid mit Methyltaurin kondensiert und das so erhaltene 1-Bromanthrachinoci-2- sulfomethyltaurid weiter mit m-Aminodime- thylanilin kondensiert. Der so erhaltene Farbstoff stellt ein grünes wasserlösliches Pulver dar, das Wolle in klaren gelbstichiggrünen Tönen färbt. PATENT CLAIM: Process for the preparation of a dye of the anthraquinone series, characterized in that 1-bromoanthraquinori- 2-sulfochloride is condensed with methyltaurine and the 1-bromoanthraquinoci-2-sulfomethyltauride thus obtained is further condensed with m-aminodimethylaniline. The dye thus obtained is a green, water-soluble powder that dyes wool in clear yellowish green tones.
