Description

  

  <B>Zusatzpatent</B> 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-Amino-          2,4-dibromanthrachiiion    mit     1-Methyl-4-amino-          benzol-2-sulfoäthanolamid    kondensiert und die  erhaltene Base durch Erhitzen mit     Sulfit    in  die     Sulfonsäure    überführt.

      <I>Beispiel:</I>  10 Teile     1.Amino-2,4-dibromanthrachinon,     <B>15</B> Teile 1-Methyl-4-aminobenzol-2-sulfoätha-         nolamid,    5 Teile     Kaliumacetat,    0,3 Teile  Kupferacetat werden in Gegenwart eines ge  eigneten Lösungsmittels; wie     Nitrobenzol-          Dimethylanilin        etc.,    so lange auf 120-150    erwärmt, bis die Kondensation nicht mehr  weiter fortschreitet. Die Base wird auf übliche  Weise isoliert und mit     Sulfiten,    vorzugsweise  in Gegenwart von Phenol, bei Temperaturen  von 100-150   behandelt.  



  Der erhaltene wasserlösliche Farbstoff be  sitzt die Formel  
EMI0001.0018     
    und färbt Wolle in lebhaften blauen Tönen an.



  <B> Additional patent </B> to main patent number 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-2,4-dibromanthrachiiion is condensed with 1-methyl-4-aminobenzene-2-sulfoethanolamide and the base obtained is converted into the sulfonic acid by heating with sulfite convicted.

      <I> Example: </I> 10 parts of 1st amino-2,4-dibromoanthraquinone, <B> 15 </B> parts of 1-methyl-4-aminobenzene-2-sulfoethanolamide, 5 parts of potassium acetate, 0, 3 parts of copper acetate are in the presence of a suitable solvent; such as nitrobenzene dimethylaniline etc., heated to 120-150 until the condensation no longer proceeds. The base is isolated in the usual way and treated with sulfites, preferably in the presence of phenol, at temperatures of 100-150.



  The resulting water-soluble dye has the formula
EMI0001.0018
    and dyes wool in vivid blue tones.
