  Zusatzpatent zum Hauptpatent     Nr.   <B>178548.</B>    Verfahren zur Herstellung eines neuen     Farbstoffes    der     Anthrachinonreihe.       Es wurde gefunden,     dass    man einen neuen  Farbstoff der     Anthrachinonreihe    erhält,  wenn man auf<B>1</B>     Mol        Cyanurchlorid    2     Mol     des Kondensationsproduktes aus     1-Amino-4-          bromanthrachinon-2-sulfonsä,ure    und derjeni  gen     Benzidinmonosulfonsäure,    die erhalten  wird durch     Sulfieren    des     Benzidins,

      und  <B>1</B>     Afol    Anilin derart einwirken     lässt,        dass     2 Halogenatome des     Cyanurchlorides    mit<B>je</B>  einem Wasserstoffatom der     Aminogruppe    des       Benzidinsulfonsäurerestes    des Kondensations  produktes und<B>1</B> Halogenatom mit einem  Wasserstoffatom der     Aminogruppe    des Ani  lins reagieren.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit blauer Farbe  löst und     Viskosekunstseide    oder Baumwolle  in reinen     grünstichig-blauen    Tönen von sehr  ,guter     Liehtechtlieit    färbt.  



  <I>Beispiel:</I>  Zu einer feinen Suspension von<B>18,5</B> Tei  len     Cyanurchlorid    in<B>800</B> Teilen Wasser wer-    den bei<B>5' 113</B> Teile des Kondensations  produktes aus     1-Amino-4-bromantlirachinon-          2-sulfonsäure    und     Benzidinsulfonsäure    in  2000 Teilen Wasser zugegeben. Man rührt  4 bis<B>5</B> Stunden bei<B>10</B> bis<B>15 '</B> und erhöht  dann die Temperatur allmählich auf<B>35</B> bis  40'. Durch     Zutropfen    einer 10%igen     Na-          triumearbonatlösung    hält man die Reaktion  stets neutral.

   Wenn die Kondensation be  endet ist, gibt man<B>18</B> Teile     Auilin    dazu und  erhitzt unter gutem Rühren noch<B>1</B> Stunde  auf<B>90</B> bis<B>95</B>     '.    Dann stellt man die Reak  tionsmasse mit     Natriumearbonat    alkalisch  und salzt den gebildeten Farbstoff aus.



  Additional patent to main patent no. <B> 178548. </B> Process for the production of a new dye from the anthraquinone series. It has been found that a new dye of the anthraquinone series is obtained if 2 moles of the condensation product of 1-amino-4-bromoanthraquinone-2-sulfonic acid and the benzidine monosulfonic acid are added to <B> 1 </B> mole of cyanuric chloride is obtained by sulfating the benzidine,

      and <B> 1 </B> Afol allows aniline to act in such a way that 2 halogen atoms of the cyanuric chloride with <B> each </B> one hydrogen atom of the amino group of the benzidinesulfonic acid residue of the condensation product and <B> 1 </B> halogen atom with one Hydrogen atom of the amino group of the aniline react.



  The new dye forms a dark powder that dissolves in water with a blue color and dyes viscose rayon or cotton in pure greenish blue tones of very, good lightness.



  <I> Example: </I> For a fine suspension of <B> 18.5 </B> parts of cyanuric chloride in <B> 800 </B> parts of water, <B> 5'113 </ B> Parts of the condensation product of 1-amino-4-bromantlirachinon- 2-sulfonic acid and benzidinesulfonic acid in 2000 parts of water are added. The mixture is stirred for 4 to <B> 5 </B> hours at <B> 10 </B> to <B> 15 '</B> and then gradually increases the temperature to <B> 35 </B> to 40' . The reaction is always kept neutral by adding a 10% sodium carbonate solution.

   When the condensation has ended, add <B> 18 </B> parts of Auilin and heat for <B> 1 </B> hour to <B> 90 </B> to <B> 95 <while stirring well / B> '. Then the reaction mass is made alkaline with sodium carbonate and the dye formed is salted out.
