Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 185420.    Verfahren zur     Darstellunr    eines     Kondensationsproduktes    der     Anthraehinonreihe.       Das vorliegende Verfahren     betrifft    die  Darstellung eines     Anthrachinonfarbstoffes    und  ist dadurch gekennzeichnet, dass man     1-Amino-          4-bromanthrachinorr-2-sulfonsäure    mit     1-Me-          thyl-4-amirrobenzol-2-sulfoäthanolamid    kon  densiert.  



  <I>Beispiel:</I>  25 Teile     1-amino-4-bromanthracliinon-2-          gulfonsaures    Natrium, 12 Teile     Natriumbi-          karbonat,    18 Teile     1-Methyl-4-aminobenzol-          2-sulfoäthanolamid,    1 Teil Kupferpulver und  300 Teile Wasser werden so lange bei  55-65   gerührt, bis die     Farbstoffbildung    been  det ist. Der in Kristallen ausgeschiedene Farb  stoff wird filtriert und vom Kupfer befreit.  



  Durch Umfällen aus heisser, verdünnter, ange  säuerter Kochsalzlösung kann der reine Farb  stoff in schönen Kristallen erhalten werden.  



  Der neue     Farbstoff    besitzt die Formel  
EMI0001.0018     
    und färbt Wolle in lebhaften blauen Tönen  an.



  <B> Additional patent </B> 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-bromoanthraquinor-2-sulfonic acid is condensed with 1-methyl-4-amirrobenzene-2-sulfoethanolamide.



  <I> Example: </I> 25 parts of 1-amino-4-bromoanthracliinon-2-sulfonic acid sodium, 12 parts of sodium bicarbonate, 18 parts of 1-methyl-4-aminobenzene-2-sulfoethanolamide, 1 part of copper powder and 300 parts Water are stirred at 55-65 until the dye formation has ended. The color precipitated in crystals is filtered and freed from copper.



  The pure color can be obtained in beautiful crystals by reprecipitation from hot, dilute, acidified saline solution.



  The new dye has the formula
EMI0001.0018
    and dyes wool in vivid blue tones.
