2-Aminophenol - Properties
The pure product is white acicular crystal, which gradually turns black in light and air. Can sublimate. Density 1 328g/cm3。 Melting point 174 ℃. Insoluble in benzene, soluble in ethanol and water. In case of ferric chloride, it is red and forms water-soluble salt with inorganic acid.
2-Aminophenol Preparation method
O-nitrochlorobenzene is heated and heated in sodium hydroxide solution, hydrolyzed under a certain pressure to obtain sodium o-nitrophenol, then reduced with alkali sulfide, acidified with carbon dioxide, cooled and filtered, immersed in sodium bisulfite solution, centrifuged and dried to obtain the finished product.
2-Aminophenol- Application
Dye intermediate, used for manufacturing sulfide dyes, azo dyes, fur dyes and fluorescent brightener E.
2-Aminophenol- Safety
Toxic. It has the toxicity of aniline and phenol. It can be absorbed through the skin and cause toxic dermatitis, methemoglobin and asthma. The production equipment shall be sealed, the site shall be well ventilated, and the operators shall wear protective equipment.
