  Verfahren zur Herstellung eines Derivates der     4,4'-Diamino-stilben-disulfonsäure-(2,2').       Es wurde gefunden, dass man zu einem  neuen Derivat der     4,4'-Diamino-stilben-disul-          fonsäure-(2,2')    gelangt, wenn man erfindungs  gemäss 1     Mol        Cy        anurchlorid    mit 1     Mol    des     Di-          natriumsalzes    der 4-[2-Ä.thylamino-4-(o-anisi-         dino)    -1,     3,5-triazyl-(6)-amino    ] -     4'-amino-stilben-          disulfonsäure-(2,2'),

      1     Mol        Methylamin    und  1     Mol        Äthanolamin    umsetzt.  



  Das so erhaltene neue     Natriumsalz    der  Formel     3s     
EMI0001.0020     
    ist ein gelbliches, wasserlösliches Pulver und       i    kann zum optischen Bleichen von     Cellulose-          fasern    verwendet werden.  



  <I>Beispiel:</I>  Durch Kondensation von 1     Mol        Cyanur-          ehlorid    mit 1     Mol        4'-Nitro-4-amino-stilben-di-          sulfonsäure-(2,2'),    1     Mol        Äthylamin    und 1     Mol          o-Anisidin    und anschliessende Reduktion wird  das     Dinatriumsalz    der     4-[2-Äthvjamino-4-(o-          anisidino)    -1,3,5 -     triazyl    - (6     )

   Es ist. ein gelb-         liches    Pulver, dessen wässerige Lösungen auf  ein     Cellulosematerial    aufgebracht, dieses im  ultravioletten Licht bläulich aufleuchten las  sen.



  Process for the preparation of a derivative of 4,4'-diamino-stilbene-disulfonic acid- (2,2 '). It has been found that a new derivative of 4,4'-diamino-stilbene-disulphonic acid- (2,2 ') is obtained if, according to the invention, 1 mol of cyano chloride with 1 mol of the disodium salt of 4- [2-Ä.thylamino-4- (o-anisidino) -1, 3,5-triazyl- (6) -amino] -4'-amino-stilbene-disulfonic acid- (2,2 '),

      Reacts 1 mole of methylamine and 1 mole of ethanolamine.



  The new sodium salt of formula 3s thus obtained
EMI0001.0020
    is a yellowish, water-soluble powder and i can be used for the optical bleaching of cellulose fibers.



  <I> Example: </I> By condensation of 1 mole of cyanuric chloride with 1 mole of 4'-nitro-4-amino-stilbene-disulfonic acid- (2.2 '), 1 mole of ethylamine and 1 mole of o- Anisidine and subsequent reduction is the disodium salt of 4- [2-Äthvjamino-4- (o- anisidino) -1,3,5 - triazyl - (6)

  -amino] -4'-aminothilbene-disulfonic acid- (2,2 '). This s is with 1 mol of cyanuric chloride, 1 mol of methylamine and 1.

       Moles of ethanolamine to the disodium salt of 4- [2-ethylamino-4- (o-anisidino) -1,3,5-triazyl- (6) -amino] -4'- [2-methy 1 amino-4 - (s-oxy-äthyIamino) -1,3,5-triazyl- (6) -amino] -stilbene-disulfonic acid- (2,2 ') implemented.

   It is. a yellowish powder, the aqueous solutions of which are applied to a cellulose material, causing it to glow bluish in ultraviolet light.
