1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene

1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene is an aminophenyl ether with two trifluoromethyl groups in the amine interstitial position is a precursor for the synthesis of polyimides, with high heat resistance (5% heat loss at 525°C), extraordinary mechanical properties (tensile strength >60 MPa, Young's modulus >4 GPa) and excellent insulating properties (breakdown strength >358 kV/mm). As a result, these polyimides can be used as insulating materials with low energy consumption. The spatial effect of the trifluoromethyl group reduces intermolecular aggregation, leading to a low refractive index and high transparency to the polyimide. The polyimides derived from 1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene can be used as interlayers for current collectors in high energy lithium-ion batteries. This type of current collectors improves 16–26% specific energy and can self-extinguish fires under short circuits.

This multi-functional diamine presents as a white to almost white crystalline powder. Store in a cool and dark place. 1,4-Bis(4-amino-2-trifluoromethylphenoxy)benzene is known to be incompatible with oxidizing agents and should not be stored or handled in their vicinity.

4,4'-[1,4-PHENYLENEBIS(OXY)]BIS[3-(TRIFLUOROMETHYL]BENZENAMINE can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development and chemical production processes.

1, 4-bis (4-amino-2-trifluoro-methylphenoxy)benzene has acute toxic effects and is harmful if swallowed, in contact with the skin or inhaled. Precautions should be taken when in use.

The mixture of 0.1 mol 1,4-bis(4-amino-2-trifluoromethyl)-benzene, 0.1 mol ODPA and 200 ml DMAc were added intoa three-necked flask. The mixture was stairred at room temperature for 4 hours and to this mixture was slowly added 30 ml Triethylamine and 80 ml Acetic anhydride. The mixture continued to stir for 30 min and then heated at 120 for 8 hours. The mixture cooled and poured into 800 ml ethanol. Filtered and dried to obtain the final product.
