Process for producing 3,3'-dinitro-5,5'-bis (trifluoromethyl) diphenyl ether |
| abstract |
(57) [Abstract] [Purpose] 3,3′-dinitro-5 represented by the following formula Provided is a method for producing 5'-bis (trifluoromethyl) diphenyl ether. [Structure] 3,5-Dinitrotrifluoromethylbenzene is self-condensed in an aprotic polar solvent in the presence of nitrite. [Effect] It is useful as a raw material of an aromatic diamine for polyimide, which has a low dielectric property and is excellent in molding processability. |
