Abstract

4,41 - Bis - (2 - chloro - 4 - ethanolamino - 1,3,5-triazyl - (6)) - diaminostilbene - 2,21 - disulphonic acid, which is fluorescent to ultra-violet light and may be used for whitening textiles, is prepared by condensing 2 mols. of cyanuric chloride with 1 mol. of a salt of 4,41-diaminostilbene-2,21-disulphonic acid and 2 mols. of monoethanolamine, in either order. When the ethanolamine is condensed in the second stage of the reaction more than 2, e.g. 5 mols. may be used. In example (1), 4,41-diaminostilbene-2,21-disulphonic acid is dissolved in aqueous caustic soda, added to a suspension of cyanuric chloride with the addition of more caustic soda, and monoethanolamine is added to the product. In example (2), monoethanolamine is added to a suspension of the disodium salt of 4,41-bis-(2,4-dichloro-1,3,5-triazyl-(6))-diaminostilbene-2, 21-disulphonic acid prepared as in (1).ALSO:4,41 - Bis - (2 - chloro - 4 - ethanolamino-1,3,5 - triazyl - (6)) - diaminostilbene - 2,21-disulphonic acid (see Group IV (b)) is fluorescent to ultra-violet light and may be used for whitening textiles.
