Description

  

      Verfahren    zur Herstellung eines neuen Farbstoffes der     Anthraehinonreihe.       Es wurde gefunden, dass man einen neuen  Farbstof<B>f</B> der     Anthrachinonreihe    erhält, wenn  man auf 1     Mol        Cyanurchlorid    1     Mol    1       Amino-4-(4'-amino)-anilidoanthrachinon-2-          sulfonsäure,    1.

       Mol        2-Amino-5-oxynaphthalin-          7-sulfonsä.ure    und 1     Mol    Anilin derart ein  wirken     lässt,    dass je ein Halogenatom des       Cyanurchlorides    durch je 1     Mol    der drei wei  teren Ausgangsstoffe ausgetauscht wird.  



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



       Beispiel:     18,5 Teile     Cyanurchlorid    werden in 800  'feilen Wasser fein suspendiert. Zu dieser  Suspension giesst man eine neutrale Lösung  von 40,8 Teilen     1-Amino-4-(4'-amino)-anilido-          anthracliinon-2-sulfonsäure    in<B>1200</B> Teilen  Wasser. Man rührt bei 20'<B>3</B> 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 28,9 Teilen     2-          Amino-5-oxynaphthalin-7-sulfonsäure    und 14  Teilen kristallisiertem     Natriumacetat    in 1000  Teilen Wasser dazu. Man erhöht nun die  Temperatur auf 40 bis 45   und rührt 24  Stunden.

   Dann wird mit Natriumkarbonat  lösung genau neutralisiert und 18,6 Teile  Anilin zugegeben. Man erhitzt das Ganze  während 2     Stunden    auf<B>90',</B> macht durch  Zugabe von Natriumkarbonat alkalisch und  salzt den gebildeten Farbstoff aus.



      Process for the production of a new dye of the anthraehinone series. It has been found that a new dye of the anthraquinone series is obtained if 1 mol of 1 amino-4- (4'-amino) -anilidoanthraquinone-2-sulfonic acid is added to 1 mol of cyanuric chloride, 1.

       Mol of 2-amino-5-oxynaphthalene-7-sulfonic acid and 1 mol of aniline can act in such a way that each halogen atom of the cyanuric chloride is replaced by 1 mol of each of the three other starting materials.



  The new dye forms a dark powder that dissolves in water with a blue color and dyes cotton, viscose rayon, wool or silk in greenish-blue shades of good lightfastness.



       Example: 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- (4'-amino) -anilido-anthracliinone-2-sulfonic acid in 1200 parts of water is poured into this suspension. The mixture is stirred at 20-3 to 4 hours and gradually 50 parts of 10% sodium carbonate solution are added so that the reaction always remains neutral. A neutral solution of 28.9 parts of 2-amino-5-oxynaphthalene-7-sulfonic acid and 14 parts of crystallized sodium acetate in 1000 parts of water are then added. The temperature is now increased to 40 to 45 and the mixture is stirred for 24 hours.

   Then it is exactly neutralized with sodium carbonate solution and 18.6 parts of aniline are added. The whole is heated to <B> 90 'for 2 hours, </B> making it alkaline by adding sodium carbonate and salting out the dye formed.
