实验过程

Cyanuric chloride (6 g) dissolved In acetone was added to ice/water with vigorous stirring followed by 2,4-diaminobenzene sulphonic acid. The mixture was stirred at 0° C. and pH3 for 1.5 hours, screened and the pH adjusted to 2.0. 2N sodium nitrite solution (16.5 ml, 0.033 moles) was added at 0° C. and pH2. After 2 hours, 1-hydroxy-7-aminonaphthalene-3-sulphonic acid (0.03 moles) was added; the mixture was stirred for 6 hours at 0° C. and pH2 to give a solution of 8-(2-sulpho-5-[dichloro-s-triazinylamino]phenylazo)-7-amino-1-hydroxynaphthalene3-sulphonic acid.
