Description

  

      Verfahren    zur Darstellung eines     Polyazofarbatoffes.       Es wurde gefunden, dass man einen werte  vollen grünen Direktfarbstoff erhält, wenn  man 2     Mol.    der     diazotierten        Aminoazover-          bindung    aus     diazotierter        4-Toluidin-3-sulfo-          säure    und     1-Amino-2-äthoxynaplhtalin-6-          sulfosäure    auf 1     Mol.    des Kondensations  produktes aus 1     Mol.        Cyanurchlorid,    2     Mol.     1 .

   8 -     Aminonaphtol    -     3,.        6,-        disulfosäure    und  1     Mol.        4-Amino-4'-oxyazobenzol-3'-carbon-          säure    kuppelt.  



       Beispiel:     Die in üblicher Weise aus 930 Gewichts  teilen des     Aminoazofarbstoffes    aus     diazotier-          ter        4-Amino-l-methylbenzol-3-sulfosäure    und       1-Amino-2-äthoxynaphtalin-6-sulfosäure    her  gestellte, abgeschiedene und mit Eiswasser       verpastete        Diazoverbindung    fliesst bei 5 bis  <B>1,0'</B> zu einer gut gerührten, zweckmässig mit       Pyridin    versetzten Lösung von 1213 Ge  wichtsteilen des Kondensationsproduktes aus  1     Mol.        Cyanurchlorid,

      2     Mol.    1 .8-Amino-         naphtol    - 3 . 6 -     disulfosäure    und 1     Mol.        4-          Amino-4'-oxyazobenzol-3'-carbonsäure.    Die  Kupplung setzt sofort unter     Tiefgrünfärbung     der Lösung ein und ist bald beendigt.  



  Der Farbstoff stellt in getrocknetem Zu  stand ein dunkles,     bronceglänzendes    Pulver  dar, das sich mit grüner Farbe in Wasser löst  und aus dem     Glaubersalz-Sodabad    in kräf  tigen,     blaustichig-grünen    Tönen von grosser  Reinheit auf die pflanzliche Faser aufzieht.  Die Färbungen besitzen eine sehr gute Licht  echtheit.



      Process for the preparation of a Polyazofarbatoffes. It has been found that a valuable full green direct dye is obtained if 2 moles of the diazotized aminoazo compound from diazotized 4-toluidine-3-sulfonic acid and 1-amino-2-ethoxynaplhtalin-6-sulfonic acid are added to 1 mole. of the condensation product from 1 mol. Cyanuric chloride, 2 mol. 1.

   8 - aminonaphtol - 3 ,. 6, - disulfonic acid and 1 mol. 4-amino-4'-oxyazobenzene-3'-carboxylic acid couples.



       Example: The diazo compound prepared in the usual way from 930 parts by weight of the aminoazo dye from diazotized 4-amino-1-methylbenzene-3-sulfonic acid and 1-amino-2-ethoxynaphthalene-6-sulfonic acid, deposited and pasted with ice water flows in 5 to <B> 1.0 '</B> to a well-stirred solution of 1213 parts by weight of the condensation product of 1 mol of cyanuric chloride, suitably mixed with pyridine,

      2 mol. 1 .8-amino naphtol - 3. 6 - disulfonic acid and 1 mole. 4-amino-4'-oxyazobenzene-3'-carboxylic acid. The coupling starts immediately with a deep green coloration of the solution and is soon over.



  When dried, the dye is a dark, bronze-shimmering powder that dissolves in water with a green color and is absorbed from the Glauber's salt soda bath in strong, bluish-green tones of great purity on the vegetable fiber. The colors have very good light fastness.
