What is 33-Diaminobenzidine?
Part I: Introduction
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 33-Diaminobenzidine which has developed particularly rapidly in recent years. Do you know about 33-Diaminobenzidine ?
The official answer:33-Diaminobenzidine is a chemical with the molecular formula C12H14N4, which is a whitish to brownish-red crystalline powder.
What’s the application of 33-Diaminobenzidine ?
33-Diaminobenzidine can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly in laboratory research and development process and chemical production processes. It is used as a monomer for high-temperature-resistant polymers. Production methods: (1) 3,3`-dichlorobenzene is used as raw material and reacted with ammonia Chemicalbook under the action of copper catalyst; (2) Benzidine is used as raw material and reacted with acetic acid to produce biphenyl diacetamide, then reacted with nitric acid to produce 3,3`-dinitrobenzene diacetamide, hydrolyzed in aqueous sulfuric acid solution to produce 3,3`-dinitrobenzene, and finally reduced by sodium sulfide The product is obtained by reduction with sodium sulfide or catalytic hydrogenation.
