Description

  

      Zusatzpatent    zum Hauptpatent Nr. 178548.    Verfahren zur Herstellung eines neuen     Farbstoffes    der     Anthraehinonreihe.       Es wurde gefunden, dass man einen neuen  Farbstoff der     Anthrachinonreihe    erhält, wenn  man auf 1     Mol        Cyanurchlorid    1     Mol        1-          Amino-4-        (3'-amino)-anilido-anthrachinon-2-          sulfosäure,    1     Mol        1-Amino-4-(4'-amino-di-          phenyl)

  -amino-anthrachinon-2-sulfosäure    und  1     Mol    Anilin derart einwirken lässt, dass je  ein Halogenatom des     Cyanurchlorides    durch  je 1     Mol    des weiteren Ausgangsstoffes ausge  tauscht wird.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit blauer Farbe  löst, und Baumwolle und     Viskoseseide,    in       blaustichigvioletten    Tönen von vorzüglicher  Lichtechtheit färbt.    <I>Beispiel:</I>    18,5 Teile     Cyanurchlorid    werden in 800  Teilen Wasser fein suspendiert. Zu dieser  Suspension giesst man eine neutrale Lösung  von 40,8 Teilen     1-Amino-4-(3'-amino)-ani-          lido-antlirachinon-2-sulfosäure    in 1200 Teilen    Wasser.

   Man rührt bei 20' 3 bis 4 Stunden  und giesst allmählich 50 Teile 10%ige Na  triumkarbonatlösung dazu, so dass die Reak  tion immer neutral     bleibt.    Dann gibt man  eine neutrale Lösung von 48,5 Teilen     1-          Amino    - 4-(4' -     amino-        diphenyl)-amino-anthra-          chinon-2-sulfosäure    und 14 Teilen kristalli  siertem     Natriumacetat    in 1000 Teilen Was  ser dazu. Man erhöht nun die Temperatur  auf 40 bis 45   und rührt 48 Stunden. Dann  wird mit     Natriumkarbonatlö.sung    genau neu  tralisiert und 18,6 Teile     Anilin    zugegeben.

    Man erhitzt das Ganze während 2     ,Stunden     auf<B>90',</B> macht durch Zugabe von Natrium  karbonat alkalisch und salzt den gebildeten  Farbstoff aus.



      Additional patent to main patent no. 178548. Process for the production of a new dye from the anthraehinone series. It has been found that a new dye of the anthraquinone series is obtained if 1 mol of 1-amino-4- (3'-amino) -anilido-anthraquinone-2-sulfonic acid, 1 mol of 1-amino-4- (4'-amino-diphenyl)

  -amino-anthraquinone-2-sulfonic acid and 1 mol of aniline can act in such a way that each halogen atom of the cyanuric chloride is exchanged for 1 mol of the further starting material.



  The new dye forms a dark powder, which dissolves in water with a blue color, and dyes cotton and viscose silk in bluish-violet shades of excellent lightfastness. <I> Example: </I> 18.5 parts of cyanuric chloride are finely suspended in 800 parts of water. A neutral solution of 40.8 parts of 1-amino-4- (3'-amino) -anilido-antliraquinone-2-sulfonic acid in 1200 parts of water is poured into this suspension.

   The mixture is stirred at 20 'for 3 to 4 hours and gradually poured in 50 parts of 10% sodium carbonate solution so that the reaction always remains neutral. Then a neutral solution of 48.5 parts of 1- amino-4- (4 '- aminodiphenyl) -amino-anthraquinone-2-sulfonic acid and 14 parts of crystallized sodium acetate in 1000 parts of water are added. The temperature is now increased to 40 to 45 and the mixture is stirred for 48 hours. Then it is exactly neutralized with sodium carbonate solution and 18.6 parts of aniline are added.

    The whole thing is heated to <B> 90 'for 2 hours, makes it alkaline by adding sodium carbonate and salting out the dye formed.
