Product Name: 2,3-Dichloroaniline CAS NO:608-27-5
Chemical & Physical Properties:
Appearance: clear light yellow liquid or solid
Boiling Point:250-252℃ at 760mmHg
2,3-Dichloroaniline is an important organic raw material intermediate. 2,3-Dichloroaniline is widely used in fine chemical industries such as pesticides, medicines, dyes and photosensitive materials.
Preparation method: 1,2,3-trichlorobenzene and ammonia are used as raw materials, copper ions are used as catalysts, quaternary ammonium salts and polyethers are used as phase transfer catalysts, and 2,3-bis is prepared by ammonolysis under certain temperature and pressure conditions Chloroaniline/2,6-dichloroaniline. Compared with the traditional 2,3-dichloroaniline/2,6-dichloroaniline process, the present invention has the advantage of using the by-product 1,2,3-trichlorobenzene in the dichlorobenzene production process as the raw material, and one-step aminolysis 2,3-Dichloroaniline/2,6-dichloroaniline is obtained.
