      Zusatzpatent    zum     Hauptpatent    Nr. 189647.    Verfahren zur Darstellung eines neuen     Anthrachinonfarbstoffes.            Das    vorliegende     Verfahren        betrifft        die          Darstellung    eines neuen     Anthrachinonfarb-          stoffes    und ist     dadurch        gekennzeichnet,     dass man     1-Am.ino-4(2'4'-@dimethyl=6'-brom-          anilido)anthrachinon-@2@sulfosäure    :

  in Gegen  wart von     Ätzkali,        Pyridin    und Nitrobenzol  mit Glyzerin     kondensiert    und die erhaltene  Verbindung mit     Schwefelsäure        behandelt.     <I>Beispiel:

  </I>  Man löst 10 Teile     Ätzkali        in    100 Teilen  Glyzerin durch     gelindes        Erwärmen,        fügt     10 Teile     1-amino-4-(2',4'-,dimethyl-6'-brom)-          phenylaminoanthraehinon-2,-s,tüfosaures    Ka  lium, 10     Teile        Pyridin    und 2 Teile     Nitro-          benzol    hinzu und rührt     bei    110  , bis     eine     in Wasser ,gezogene     Probe        keine    blaue Lö  sung mehr gibt.

   Man verdünnt mit heissem       Wasser,    saugt ab und wäscht     .gründlich    aus.       Die    getrocknete     Base    wird in Monohydrat       verestert    und der     entstandene        Farbstoff     durch Verdünnen der     Reaktionsmasse    mit  Eis- und     Salzwassermischung    ausgefällt,  filtriert,

       gewaschen    und in üblicher     Weise     nach der     Neutralisation        isoliert.       Der neue Farbstoff besitzt die     Formel     
EMI0001.0049     
    und färbt Wolle     in    lebhaften     rotstichig        vio-          letten    Tönen von     sehr    guten     Echtheiten    an.



      Additional patent to the main patent No. 189647. Process for the preparation of a new anthraquinone dye. The present process relates to the preparation of a new anthraquinone dye and is characterized in that 1-Am.ino-4 (2'4 '- @ dimethyl = 6'-bromo anilido) anthraquinone @ 2 @ sulfonic acid:

  in the presence of caustic potash, pyridine and nitrobenzene condensed with glycerine and treated the compound obtained with sulfuric acid. <I> example:

  </I> 10 parts of caustic potash are dissolved in 100 parts of glycerine by gentle heating, 10 parts of 1-amino-4- (2 ', 4' -, dimethyl-6'-bromo) - phenylaminoanthraehinon-2, -s, tüfosaures are added Add potassium, 10 parts pyridine and 2 parts nitrobenzene and stir at 110 until a sample taken in water no longer gives a blue solution.

   It is diluted with hot water, suctioned off and thoroughly washed out. The dried base is esterified in monohydrate and the resulting dye is precipitated by diluting the reaction mass with an ice and salt water mixture, filtered,

       washed and isolated in the usual way after neutralization. The new dye has the formula
EMI0001.0049
    and dyes wool in lively reddish purple tones with very good fastness properties.
