실험 절차

Disodium 4,4'-bis(4,6-dichloro-s-triazin-2-ylamino)-2,2'-stilbenedisulfonate was prepared by interaction of 500 pounds of 4,4'-diamino-2,2'-stilbenedisulfonic acid with a solution of 500 pounds of cyanuric chloride in 2100 pounds of acetone in an aqueous reaction medium at pH 7-8 prepared by mixing 3200 pounds of crushed ice and approximately 2100 pounds of 10 percent aqueous sodium hydroxide solution. The disodium 4,4'-bis(4,6-dichloro-s-triazin-2-ylamino)-2,2'-stilbenedisulfonate thus obtained was mixed with 270 pounds of disodium phosphate and interacted at 15°-50° C with 625 pounds of aniline for thirty minutes and then the pH of the reaction mixture was adjusted to 6.7-6.8 by adding approximately 600 pounds of 10 percent aqueous sodium hydroxide solution during a period of one hour.
