UNSATURATED DERIVATIVES OF 4, 4 - DI (TRIAZINYL) AMINOSTILBENDISYLPHOACIDE- 2, 2 - AND METHOD FOR THEIR PREPARATION

摘要

These compounds are used as optical bleaches for textiles, paper and polymeric products. They contribute to the improvement of the quality of whiteness and have the following general formula:<IMAGE>in which A1 is aniline or morpholine residue and A2 is residue of unsaturated alcohol. The method for their preparation involves reacting 4,4'-diaminostilbenedisulphonic acid-2,2' with 2-allyloxy-4-anilino/morpholino/-6-chloro-1,3,5-triazine in a water-acetone suspension at temperatures between 70 and 100 degrees C and pH 7-7.5.
