Versuchsvorschrift
An ice cold neutral solution of 1-hydroxy-8-aminonaphthalene-3,6-disulphonic acid (31.9 parts) in water (120 parts) was added, with stirring, to a freshly prepared suspension of 2,4,6-trichloro-s-triazine (18.5 parts) in ice and water (140 parts). The mixture was stirred for 3 hours at 0 to 5° C. to give a solution of 1-hydroxy-8-(2,4-dichloro-s-triazin-6-ylamino-)naphthalene-3,6-disulphonic acid (solution 1).
