4,4'-[1,4-페닐렌비스(옥시)]비스[3-(트리플루오로메틸]벤제나민 C화학적 특성, 용도, 생산
개요
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.
화학적 성질
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.
용도
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.
Synthesis
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.
