This product is the intermediate of various dye products such as direct dyes, acid dyes, ice dyes and disperse dyes. It is also the main raw material of various rubber antioxidant. 1-naphthol produced by 1-naphthylamine is an important intermediate of carbaryl pesticide. 1- naphthalene can be absorbed by skin, resulting in the high speed rail hemoglobin, which causes poisoning, causing urinary system diseases and chronic poisoning, which can cause bladder cancer. The maximum allowable dissolved concentration in the air is 0.001mg/l.

Properties

Aromatic amines are a kind of important nitrogen-containing compounds, which are widely used in explosives, dyes and pharmaceutical industries. The synthesis method is generally based on well-known reactions. Simple aromatic amines can be prepared by reduction of nitro compounds or by k-amino substitution of halogenated aromatics. In addition, there are other special preparation methods. in recent years, α- Naphthylamine (also known as 1-naphthylamine) has been well used in dye chemical industry and organic synthesis, especially in the synthesis of axial chiral catalysts.
