Hierauf steigert man die Temperatur  auf 60  C und hält. kurze Zeit. bei dieser Tem  peratur.

   Nach dem Abkühlen hat sich das ent  standene     Kondensationsprodukt    teilweise ab  geschieden; der Rest wird mit     Natriumehlorid     gefällt.     1 < 1an    filtriert, wäscht mit     Natriumehlo-          ridlösung    und trocknet.    Das neue Produkt stellt. ein helles Pulver  dar, das in Wasser löslich ist.



  Process for the preparation of a derivative of 4,4'-diamino-stilbene-disulfonic acid- (2,2 '). It was found that a new derivative of 4,4'-diamino-stilbene-disulphonic acid- (2,2 ') is obtained if 1 mol of the disodium salt of 4-amino-4' - [2 -methyl amino-4- (f3-oxyethyl-amino) -1,3,5-t.riazyl- (6) -aminol-stilbene-disulfonic acid 1ire- (2,2 '),

      produced by condensation of 1 mole of Cvanurehlorid with 1 mole of the disodium salt of 4-nitro-4'-amino-stilbene-disulfonic acid- (2.2 '), 1 mole of ethanolamine and 1 mole of monomethylamine and subsequent reduction of the nitro body to the amine, with 1 1Tol phenyl isoevanate.

      The reaction can be carried out, for example, in such a way that 1 mole of the disodium salt mentioned is reacted at 60 in aqueous solution with the phenyl isocyanate.



  The thus obtained new disodium salt of the formula
EMI0001.0027
         21) forms a light-colored powder that, when applied to cellulose material in aqueous solution, is exposed to ultraviolet light. lights up bluish. <I> example:

  </I> To a 50 C warm, neutral solution of .5.4 parts of the disodium salt of 4-amino-4'- [2-methylamino-4- (fl-oxy-ethyl-a.mino) -1,3 , 5-triazyl - (6) -amino] - stilbene - disulphonic acid- (2,2 '), prepared by condensation of 1 mol of vanuric chloride with 1 mol of the disodium salt of 4-nitro-4'-amizio-stilbene disulfonic acid- (2.2 '),

      1 14lol ethanolamine and 1 llol Monomethy lamin and subsequent reduction of the nitro body to the amine, in 50 parts of water with thorough stirring, 2 parts of phenyl isocyanate dissolved in 5 parts of acetone within about. Added dropwise for 10 minutes. The temperature is then increased to 60 ° C. and held. short time. at this temperature.

   After cooling, the condensation product formed has partially separated off; the rest is precipitated with sodium chloride. 1 <1an filtered, washed with sodium chloride solution and dried. The new product represents. is a light-colored powder that is soluble in water.
