P-NITROSODIPHENYLAMINE - Production method
30g aniline, 30g nitrobenzene and 120g dried sodium hydroxide powder are mixed evenly, heated to 110-120 ℃, stirred to become dilute liquid, then heated to 120-125 ℃, the color of the reaction liquid becomes darker and thicker, when the reaction liquid is cured, the reaction reaches the end point. Cool, dissolve in hot water, cool, filter, filter out blue-black needle crystals after passing carbon dioxide. The filtrate is then passed through carbon dioxide to filter out the second batch of products. Two batches of products were combined and recrystallized with ethanol to obtain pure nitro diphenylamine.
