| titleOfInvention | Process for Producing 2,2'-Bis(Trifluoromethyl)-4,4'-Diaminobiphenyl |
| abstract | A process for producing 2,2′-bis (trifluoromethyl)-4,4′-diaminobiphenyl which is useful as a raw material for polyimide resin, etc. n In benzidine rearrangement of 3,3′-bis(trifluoromethyl) hydrazobenzene in the presence of an inorganic acid such as sulfuric acid aqueous solution or concentrated hydrochloric acid, use of a water-immiscible organic solvent such as toluene as reaction solvent can increase the yield of the product. n 3,3′-bis(trifluoromethyl) hydrazobenzene can be synthesized by reduction of m-nitrobenzotrifluoride. |
