  Verfahren zur Herstellung neuer Derivate der     4,4'-Diaminostilben-disulfonsäure-(2,2')       Es     wurde    gefunden, dass man zu neuen       wertvollen    Derivaten der     4,4'-Diaminost.ilben-          disitlfonsätire-(2;

  3')    gelangt, wenn man 1     Mo1            Cy        anur        chlorid    einerseits mit 1     Mol    einer Ver  bindung der Formel  
EMI0001.0011     
    worin v,     w    und x substituierte oder     unsubsti-          tuierte        Aminogruppen    bedeuten, und ander  seits mit 1     Mol    einer     Mereaptoverbindung    und  1     Mol    einer Verbindung mit     reaktionsfäbigem          basischem    Stickstoffatom kondensiert.

      Die neuen Verbindungen können zum Auf  hellen von     Cellulosematerialien    verwendet  werden.  



  <I>Beispiel</I>  Man stellt das Kondensationsprodukt der  Formel  
EMI0001.0022     
         ber,    indem man 1     3To1        Cyanurchlorid    mit  1     Mol        4-Amino-4'-    [2 -     (ss-        oxyäthylamino)    -     4-          anilino-1,3,5-triazyl    - (6) -     amino    ] -     stilben-        disul-          fonsz.iure-(2,2'),    1     Mol        4-Nitro-4'-aminostilben-          disulfonsäure-(2,2')

      und 1     Mol        Monoäthanol-          amin    kondensiert und das erhaltene Konden  sationsprodukt     naeh        Beeliamps    reduziert.    Eine Lösung von 18,5 Teilen     Cy        anur-          ehlorid    in 100 Teilen Aceton wird in eine  Mischung aus 100 Teilen Eis und 100 Teilen  Wasser eingerührt und zu der erhaltenen  Suspension bei 0 bis 5  innerhalb von 10 bis  20 Minuten eine mit     Natriumearbonat    neutral  gestellte Lösung von 119,

  3 Teilen des oben      dargestellten     Kondensationsproduktes    in 1000  Teilen Wasser unter Rühren     zugetropft.    Hier  auf     lä.sst    man zu dem erhaltenen Reaktions  gemisch innerhalb von einer Stunde eine Lö  sung von 5,5 Teilen     Natriumcarbonat    in  50 Teilen Wasser in der Weise     zutropfen,     dass das Gemisch immer neutral bis schwach  sauer reagiert. Zu der nun keine freien     Amino-          gruppen    mehr enthaltenden Suspension wer  den 12,4 Teile     4-Methylthiophenol    zugesetzt.

    Anschliessend steigert man die Temperatur  innerhalb einer Stunde auf 40  und rührt  4 Stunden bei 44 bis 45 , wobei man während  der     ganzen    Zeit die entstandene Salzsäure  durch allmähliches     Zutropfen    von 100 Teilen       n-Natriumhy        droxydlösung    neutralisiert. Nun  fügt man noch 15,2 Teile     Monoäthanolamin            zu    dem Reaktionsgemisch, steigert die Tempe  ratur innerhalb 1 bis 2 Stunden auf 60  und  rührt während 15 bis 18 Stunden bei 60 bis  65 .  



  Das gebildete Kondensationsprodukt wird  durch     Zugeben    von     Natriumehlorid    abgeschie  den, filtriert, mit     Natriumehloridlösung    ge  waschen und getrocknet.  



  Die eingangs erwähnte     4-Amino-4'-[2-(ss-          oxyäthylamino)    - 4 -     anilino    -1,3,5     -triazyl    - (6)     -          amino]-stilben-disillfonsä.ure-(2,2')    wird durch  Kondensation von 1     Mol        Cvanurchlorid    mit.

    1     Mol    Anilin, 1     Mol        Monoäthanolamin    und  1     Mol        4-Amino-4 -nitrostilben-disulfonsäiire-          (?,2')    und anschliessende Reduktion nach     Be-          champs    hergestellt.



  Process for the preparation of new derivatives of 4,4'-diaminostilbene-disulfonic acid- (2,2 ') It has been found that new valuable derivatives of 4,4'-diaminostilbene-disulfonic acid- (2;

  3 ') if you get 1 Mo1 Cy anur chloride on the one hand with 1 mol of a compound of the formula
EMI0001.0011
    where v, w and x denote substituted or unsubstituted amino groups, and on the other hand condensed with 1 mol of a mereapto compound and 1 mol of a compound having a reactive basic nitrogen atom.

      The new compounds can be used for lightening cellulosic materials.



  <I> Example </I> The condensation product of the formula is prepared
EMI0001.0022
         by adding 1 3To1 of cyanuric chloride with 1 mol of 4-amino-4'- [2 - (ss- oxyäthylamino) - 4- anilino-1,3,5-triazyl - (6) - amino] - stilbene-disulfonsz .iure- (2.2 '), 1 mol of 4-nitro-4'-aminostilbene-disulfonic acid- (2.2')

      and 1 mol of monoethanolamine condensed and the condensation product obtained was reduced after Beeliamps. A solution of 18.5 parts of cyanuryl chloride in 100 parts of acetone is stirred into a mixture of 100 parts of ice and 100 parts of water and a solution of sodium carbonate neutralized with sodium carbonate is added to the resulting suspension at 0 to 5 within 10 to 20 minutes 119

  3 parts of the condensation product shown above in 1000 parts of water were added dropwise with stirring. Here, a solution of 5.5 parts of sodium carbonate in 50 parts of water is added dropwise to the reaction mixture obtained in the course of one hour in such a way that the mixture always reacts neutrally to slightly acidic. 12.4 parts of 4-methylthiophenol were added to the suspension, which no longer contained any free amino groups.

    The temperature is then increased to 40 within one hour and the mixture is stirred for 4 hours at 44 to 45, during which the hydrochloric acid formed is neutralized by the gradual dropwise addition of 100 parts of n-sodium hydroxide solution. 15.2 parts of monoethanolamine are now added to the reaction mixture, the temperature is increased to 60 within 1 to 2 hours and the mixture is stirred at 60 to 65 for 15 to 18 hours.



  The condensation product formed is deposited by adding sodium chloride, filtered, washed with sodium chloride solution and dried.



  The 4-amino-4 '- [2- (ss- oxyäthylamino) -4 - anilino -1,3,5-triazyl- (6) -amino] -stilbene-disilfonic acid (2,2') mentioned at the beginning is made by condensation of 1 mol of Cvanurchlorid with.

    1 mole of aniline, 1 mole of monoethanolamine and 1 mole of 4-amino-4 -nitrostilbene-disulfonic acid (?, 2 ') and subsequent reduction according to Bechamps.
