Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 185420.    Verfahren zur Darstellung eines     Kondensationsproduktes    der     Anthraehinonreihe.       Das vorliegende Verfahren betrifft die  Darstellung eines     Anthrachinonfarbstoffes    und  ist dadurch gekennzeichnet, dass man     1-Amino-          4-bromanthr#achinon-2-sulfonsäure    mit     1-Me-          thyl-4-aminobenzol-2-sulfomethyl-ätharrolamid          kondensiert.     



  <I>Beispiel:</I>  10 Teile     1-amino-4-bromanthrachinon-2-          sulfonsaures    Natrium, 8 Teile     1-Methyl-4-          aminobenzol-2-sulfomethyläthanolamid,    10  Teile     Natriumbikarbonat,    0,4 Teile Kupfer  pulver und 250 Teile Wasser werden in C02  Atmosphäre so lange bei 60   gerührt, bis die  Umsetzung beendet ist.  



  Der erhaltene Farbstoff besitzt die Formel  
EMI0001.0016     
    und färbt Wolle in blauen Tönen an.



      Additional patent to the main patent No. 185420. Process for the preparation of a condensation product of the anthraehinone series. The present process relates to the preparation of an anthraquinone dye and is characterized in that 1-amino-4-bromanthralphinone-2-sulfonic acid is condensed with 1-methyl-4-aminobenzene-2-sulfomethyl-etharrolamide.



  <I> Example: </I> 10 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid sodium, 8 parts of 1-methyl-4-aminobenzene-2-sulfomethylethanolamide, 10 parts of sodium bicarbonate, 0.4 part of copper powder and 250 Parts of water are stirred in a CO 2 atmosphere at 60 until the reaction has ended.



  The dye obtained has the formula
EMI0001.0016
    and dyes wool in blue tones.
