Description

  

  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    2     Mol     1 .     4-Diaminoanthrachinon-2    .

       6-disulf        onsäure     und 1     Mol    Anilin derart einwirken lässt, dass  je zwei Halogenatome des     Cyanurchlorids     durch je 1     Mol    des     Diaminoanthrachinon-          derivates    und das dritte Halogenatom durch  1     Mol    Anilin ausgetauscht werden.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit blauvioletter  Farbe löst, und     Viskosekunstseide,    Wolle  oder Seide 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 39,8 Teilen 1     .4-Diaminoanthrachinon-          2.6-disulfonsäure    in 1200 Teilen Wasser.

    Man rührt bei 20   3 bis 4 Stunden und    giesst allmählich 50 Teile 10%ige Natrium  karbonatlösung dazu, so dass die     Reaktion     immer neutral bleibt.     Dann    gibt man eine  neutrale Lösung von weiteren 39,8 Teilen  1 .     4-Diaminoanthrachinon-2.        6-disulf        onsäure     und 14 Teilen kristallisiertem     Natriumazetat     in 1000 Teilen Wasser dazu. Man erhöht  nun die Temperatur auf 40 bis 45       und     rührt 24 Stunden. Dann wird mit Natrium  karbonatlösung 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 2 moles of 1 per mole of cyanuric chloride are used. 4-diaminoanthraquinone-2.

       6-disulphonic acid and 1 mol of aniline can act in such a way that every two halogen atoms of the cyanuric chloride are replaced by 1 mol of the diaminoanthraquinone derivative and the third halogen atom is replaced by 1 mol of aniline.



  The new dye forms a dark powder that dissolves in water with a blue-violet color and dyes viscose artificial silk, wool or silk in blue-tinged 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 39.8 parts of 1,4-diaminoanthraquinone-2,6-disulfonic 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 a further 39.8 parts of 1 is added. 4-diaminoanthraquinone-2. 6-disulfonic acid and 14 parts of crystallized sodium acetate in 1000 parts of water. 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.
