Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 178548.         Verfahren    zur Herstellung eines neuen Farbstoffes der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen  Farbstoff der     Anthrachinonreihe    erhält,  wenn man auf 1     Mol        Cvanurchlorid    1     Mol     1 .     4-Diaminoanthrachinon-2    .

       6-disulf        onsäure,     1     Mol        2-Amino-5-oxynaphthalin-7-sulfon-          säure    und 1     Mol    Anilin derart einwirken       lässt,    dass je ein Halogenatom des     Cyanur-          chlorides    durch je 1     Mol    der drei weiteren  Ausgangsstoffe ausgetauscht wird.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit     violetter     Farbe löst, und     Viskosekunstseide,    Wolle  oder Seide in reinen violetten Tönen von vor  züglicher Lichtechtheit färbt.  



  <I>Beispiel:</I>  18,5     'feile        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        Natriumkar-          bonatlösung    dazu, so dass die Reaktion immer  neutral bleibt.     Dann    gibt man eine neutrale  Lösung von 23,9 Teilen     2-Amino-5-oxynaph-          thalin-7-sulfonsäure    und 14 Teilen kristalli  siertem     Natriumacetat    in 1000 Teilen Was  ser dazu. Man erhöht nun die Temperatur  auf 40 bis 45   und rührt 24 Stunden. Dann  wird mit     Natriumkarbonatlösung    genau neu  tralisiert und<B>18,6</B> Teile Anilin zugegeben.

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



  <B> Additional patent </B> to main patent no. 178548. 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 1 mol of 1 mol of vanuric chloride is added to 1 mol of cvanuric chloride. 4-diaminoanthraquinone-2.

       6-disulphonic acid, 1 mol of 2-amino-5-oxynaphthalene-7-sulphonic 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 violet color and dyes viscose rayon, wool or silk in pure violet tones that are extremely lightfast.



  <I> Example: </I> 18.5 'file 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 50 parts of 10% sodium carbonate solution are gradually poured in so that the reaction always remains neutral. Then you add a neutral solution of 23.9 parts of 2-amino-5-oxynaphthalene-7-sulfonic 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 <B> 18.6 </B> parts of aniline are added.

    The whole is heated to 90 for 2 hours, made alkaline by adding sodium carbonate and salted out the dye formed.
