| introduction | 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. Regarding the synthesis line of 2, 3-dichloroaniline, it mainly uses 2, 3-dichloronitrobenzene as raw material. Some studies have mentioned that tungsten carbide is used as a catalyst for hydrogenation and reduction. The main problem is that the hydrogenation process requires high equipment materials and has certain safety hazards; second, the preparation and purification routes of 2, 3-dichloronitrobenzene are relatively cumbersome, resulting in higher raw material costs. |
| preparation method | using 1,2, 3-trichlorobenzene and ammonia water as raw materials, metal copper ions as catalysts, quaternary ammonium salts and polyethers as phase transfer catalysts, 2, 3-dichloroaniline/2, 6-dichloroaniline was prepared by ammonolysis under certain temperature and pressure conditions. Compared with the traditional 2,3-dichloroaniline/2,6-dichloroaniline process, the advantages of the present invention are: 1,2,3-trichlorobenzene is used as raw material in the production process of dichlorobenzene, and 2,3-dichloroaniline/2,6-dichloroaniline is obtained by one-step ammonolysis. |
| Use | Used as an intermediate for medicine and pesticide |
