Die  ses wird durch Kondensation zuerst. mit 1     Mol          Cyanurchlorid    in das     Dinatriumsalz    der     4-          [2,4-Diehlor-1,3,5-trazyl-        (6)-amino]-4'-    [2       morpholino-4-(o-anisidino)-1,3,5-triazyl-(6)-          amino]        -stilben-disulfonsäure-    (2,2')

   überge  führt und dieses Kondensationsprodukt durch  Reaktion mit 1     lIol        Isopropylamin    zum Di-         natriumsalz    der     4-[2-Isopropyl-amino-4-chlor-          1,3,5-t.r        iazyl-    (6)     -amino    ] -4'- [     2-morpholino-4-        (o-          anisidino)    -1.,3, 5 -     triazyl    - (6)     -amino    ]     -stilben-di-          sulfonsäure-(2,2')    umgesetzt, das ein hellgelb  gefärbtes, in Wasser lösliches Pulver ist.



  Process for the preparation of a derivative of 4,4'-diamino-stilhen-disulfonic acid- (2,2 '). It was found that a new derivative was found. 4,4'-diamino-st.ilbene-disulphonic acid- (2,2 ') is obtained if, according to the invention, 1 mol of the disodium salt of 4- [2,4-diehlor-1,3,5-triazy 1 - (6) -amino] -4'- [2-morpholino - 4 - (o - anisidino) -1,3,5 - triazyl- (6)

       -amino] - stilbene-disulfonic acid- (2,2 ') with 1 mole of isopropylamine. The new sodium salt of the formula thus obtained
EMI0001.0021
    is. a light yellow, water-soluble powder and can be used for optical bleaching of cellulose fibers.

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

       - amino -] - stilbene-disultonic acid- (2,2 '). This is done through condensation first. with 1 mol of cyanuric chloride into the disodium salt of 4- [2,4-Diehlor-1,3,5-trazyl- (6) -amino] -4'- [2 morpholino-4- (o-anisidino) -1,3 , 5-triazyl- (6) -amino] -stilbene-disulfonic acid- (2,2 ')

   and this condensation product by reaction with 1 lol isopropylamine to the disodium salt of 4- [2-isopropyl-amino-4-chloro-1,3,5-triazyl- (6) -amino] -4'- [2 -morpholino-4- (o-anisidino) -1., 3, 5 - triazyl - (6) -amino] -stilbene-disulfonic acid- (2,2 ') implemented, which is a light yellow colored, water-soluble powder is.
