실험 절차

The dyestuff used in Example 204 had been prepared as follows: 900 parts of n-butanol saturated with ammonia are mixed with 550 parts of 79% 4-chloro-3-nitrobenzene sulphochloride and the mixture is stirred at 55° - 60°C for 1 hour. 200 Parts aniline were added and the mixture was heated to boiling temperature while slowly introducing ammonia, until the dyestuff formation was completed. After cooling, the crystallised product was filtered off with suction, washed with methanol and water and after drying there were obtained 460 parts 4-phenylamino-3-nitrobenzene-sulphonic acid amide = 92% of theory; m.p. 155°C.
