Application: 3,3'-diaminobenzidine can be used as organic synthesis intermediate and pharmaceutical intermediate,
Mainly used: used in laboratory research and development process and chemical production process. Use as a monomer for high temperature resistant polymers
Production method: (1) 3,3`-dichlorobenzidine is used as raw material, and is obtained by reacting with ammonia under the action of copper catalyst; (2) using benzidine as raw material, reacting with acetic acid to generate biphenyl diacetamide, Then react with nitric acid to generate 3,3`-dinitrobiphenyl diacetamide, which is hydrolyzed in aqueous sulfuric acid to generate 3,3`-dinitrobenzidine, which is finally reduced with sodium sulfide, or reduced by catalytic hydrogenation.
