How to prepare aniline from benzene
There are two main methods to produce aniline in industry: ① Catalytic hydrogenation of active copper to prepare nitrobenzene. The method can be used for continuous production without pollution. (2) Chlorobenzene and ammonia react at high temperature in the presence of copper oxide catalyst. Aniline is an important chemical raw material, which is mainly used in medicine and rubber vulcanization accelerator, and is also the raw material for manufacturing resins and coatings. Aniline is very toxic to blood and nerves, and can be absorbed through the skin or cause poisoning through the respiratory tract.
