摘要:
A process for the chlorination of alkylanilines is provided allowing a highly selective chlorination in the meta-position of the aromatic ring. This is achieved by reacting a mixture comprising the alkylaniline and sulfuric acid with chlorine. This process allows a meta-chlorination with a selectivity of more than 90%.

摘要:
The present invention is a method for producing of 2,2'-bis(trifluoromethyl)-4,4'-diaminobiphenyl, wherein 2,2'-bis(trifluoromethyl)biphenyl is produced from o-chlorobenzotrifluoride, further, 2,2'-bis(trifluoromethyl)biphenyl is dinitrated in 1,2-dichloropropane solution, and 2,2'-bis(trifluoromethyl)-4,4'-dinitrobiphenyl is isolated and reduced. The method for producing of 2,2'-bis(trifluoromethyl)-4,4'-diaminobiphenyl of the present invention is an industrially excellent method for producing with high safety and high production efficiency.
