| use | as an intermediate for drugs and dyes. |
| production method | prepared by nitration of acetanilide. 675kg of 98% sulfuric acid was added into a nitrification pot, stirred, and 225kg of 99% acetanilide was added within 20-25 ℃ for 2-2.5h hours. After all dissolution, the temperature is reduced to 7 ℃, and mixed acid (made of 63kg of water, 60kg of 98% sulfuric acid and 107kg of 96% nitric acid) is added dropwise within about 20h at 4-7 ℃. After dropping, dilute in 4000L ice water and let stand for 1h. Siphon separates the upper waste acid, filters the lower material, and washes it to neutral to obtain 4-nitroacetanilide. Another preparation method is obtained by acetylation of p-nitroaniline. |
