clear light yellow to yellow-brown liquid

3,5-Bis(trifluoromethyl)aniline was used in the synthesis of N-[2-hydroxy-1-naphthylidene]-3, 5-bis(trifluoromethyl)aniline, Schiff?s base and 5,7-bis(trifluoromethyl)aniline. It was also used in the synthesis of N-1-phenylethyl-3,5-bis(trifluoromethyl)aniline via titanium-catalyzed hydroamination reaction and N,N?-bis[3,5-bis(tri-fluoromethyl)phenyl]thiourea, organocatalyst.

The synthesis of 3,5-Bis(trifluoromethyl)aniline is as follows is as follows：Put 259g (1mol) 3,5-Bis(trifluoromethyl)nitrobenzeneand 500g ethyl acetate into a 1L autoclave, add 5g palladium-carbon as a catalyst, raise the temperature to 60℃, then pass the hydrogen pressure to 2MPa, keep the temperature and react for 20 hours, then cooling, filtration, concentration, and distillation to obtain 3,5-Bis(trifluoromethyl)aniline with a purity of 98.5% and a yield of 87%.
