  <B>Zusatzpatent</B> zum Hauptpatent Nr. 242846.    Verfahren     zur        Herstellung    eines neuen     sauren        Anthrachinonfarbstoffes.       Das vorliegende Patent betrifft ein Ver  fahren zur Herstellung eines sauren     Anthra-          chinonfarbstoffes    und ist dadurch gekenn  zeichnet, dass man auf     1-Amino-(2'4'6'-tri-          methylphenylamino)-anthrachinon    - 2 -     sulf    an     -          säure    Chlor     einwirken    lässt.  



  <I>Beispiel:</I>  20 Teile     1-Amino-4-(2'4'6'-trimethylphe-          nylamino)    -     anthrachinon    - 2 -     sulfonsaures    Na-         trium    werden unter gutem Rühren bei 10 bis  20  in 120 Teilen     Oleum    von 3-4% gelöst,  worauf noch 0,2 Teile Jod zugegeben werden.  Hierauf werden langsam 3,4     Teile    Chlor ein  geleitet. Nach beendeter     Reaktion.    wird in  bekannter Weise aufgearbeitet. Der erhaltene  Farbstoff färbt Wolle     in    sehr lebhaften,  echten,     rötlichblauen    Tönen.

   Er löst sich     in     Schwefelsäure     conc.    mit blauer Farbe und  hat die Formel:  
EMI0001.0025     




  <B> Additional patent </B> to main patent no. 242846. Process for the production of a new acidic anthraquinone dye. The present patent relates to a process for the production of an acidic anthraquinone dye and is characterized in that 1-amino- (2'4'6'-trimethylphenylamino) -anthraquinone-2-sulfan-acid chlorine act leaves.



  <I> Example: </I> 20 parts of 1-amino-4- (2'4'6'-trimethylphenylamino) - anthraquinone - 2 - sulfonic acid sodium are converted into 120 parts of oleum with thorough stirring at 10 to 20 parts of 3-4% dissolved, whereupon 0.2 parts of iodine are added. 3.4 parts of chlorine are then slowly passed in. After the reaction has ended. is worked up in a known manner. The dye obtained dyes wool in very vivid, genuine, reddish-blue tones.

   It dissolves in sulfuric acid conc. with blue color and has the formula:
EMI0001.0025
