Product Description

危化品许可证.jpg

Nature Description

White or brown acicular or tabular crystal. Melting point 186-189 ℃. Boiling point 110℃(40Pa). Soluble in hot water, ethanol, propyl alcohol and alkali solution, insoluble in benzene and chloroform. After insoluble in alkali solution, it quickly turns brown. When it comes to acid and alkali, it can form a salt that is easily soluble in water. When it comes to ferric chloride or bleaching powder, the aqueous solution is purple. Heating can sublimate.

Product Applications

It is used to manufacture dyes, drugs, plastic curing agents, etc.

Production method

There are iron powder reduction method, phenol nitrosation method, coupling reduction method, etc. 1. Iron powder reduction method is obtained by reduction of P-nitrophenol. Raw material consumption quota: nitrophenol (industrial product) 1388 kg/t; Iron powder 1778 kg/t;30 hydrochloric acid 200 kg/t. 2. Phenol Nitrosation is obtained from phenol through nitrosation, reduction and acid out. 3. Coupling reduction method uses aniline as raw material and is obtained by diazotization, coupling and reduction of iron powder. 4. The catalytic hydrogenation of nitrobenzene mostly uses platinum, palladium or both as catalysts, and is hydrogenated and reduced to phenylhydroxylamine in 10-20 sulfuric acid aqueous solution, and then translocates p-aminophenol, with a yield of 70-80. Adding surfactant to the reaction system has certain effect on improving the yield. 5. Nitrobenzene electrolytic reduction method Japan Mitsui East pressure Fine Chemicals company adopts electrolytic reduction of nitrobenzene in sulfuric acid solution, and translocates to p-aminophenol through phenylhydroxylamine.
