Production methods
By acetyl aniline via nitrification. Adding 98% of the 675 kg sulfate nitrifying pot, stir, and 20 to 25 ℃, 2-2.5 h add 99% of acetanilide 225 kg. After being dissolve, cooled to 7 ℃, within 4-7 ℃ about 20 h and mixed acid (by 63 kg of water, 60 kg98 kg96 % % sulphuric acid and 107 with the nitrate). Add finished, dilution in 4000 l of ice water, let stand for 1 h. Siphon to separate the upper waste acid, will lower material filtration, washed with water to neutral, a quick 4 - nitro acetanilide. Another method is to use of nitroaniline by acetylation.
