Description

  

  Zusatzpatent zum Hauptpatent     Nr.    185420.    Verfahren zur Darstellung eines     Kondensationsproduktes    der     Anthrachinonreihe.       Das vorliegende Verfahren betrifft die  Darstellung eines     Anthrachinonfarbstoffes    und  ist dadurch gekennzeichnet, dass man     1-Arnino-          4-bromanthrachinoci-2-sulfonsäure    mit     1-Me-          thyl-4-aminobenzol-2-sulfodiäthanolamid    kon  densiert.  



  <I>Beispiel:</I>  25 Teile     1-amino-4-bromanthrachinorr2-sul-          fonsaures    Natrium, 25 Teile     Bikarbonat,     30 Teile     1-Methyl-4-aminobenzol-2-sulfodi-          äthanolamid,    1 Teil Kupferpulver und 650  Teile Wasser werden so lange auf<B>600</B> er  wärmt, bis die Menge des gebildeten Farb  stoffes nicht mehr zunimmt. Der isolierte  Farbstoff besitzt die Formel  
EMI0001.0014     
    und färbt Wolle in blauen Tönen an.



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



  <I> Example: </I> 25 parts of 1-amino-4-bromoanthraquinor-2-sulphonic acid sodium, 25 parts of bicarbonate, 30 parts of 1-methyl-4-aminobenzene-2-sulfodiethanolamide, 1 part of copper powder and 650 parts Water is heated to <B> 600 </B> until the amount of colorant no longer increases. The isolated dye has the formula
EMI0001.0014
    and dyes wool in blue tones.
