Abstract
The 1,3-bis(4-nitrophenoxy)benzene was synthesized from the condensation reaction of resorcinol with 4-nitrochlorobenzene.The 1,3-bis(4-aminophenoxy) benzene was prepared from the reduction reaction of 1,3-bis(4-nitrophenoxy) benzene in ethanol solvent with FeCl3.6H2O and C as catalyst,the hydrazine hydrate as reducing agent,and the reaction progress was tracked and studied by thin-layer chromatography(TLC) method,and the structure of target produce was characterized by melting point apparatus,DSC,FT-IR,1H-NMR spectra and elemental analysis etc.ways.The testing results showed when the mass of 1,3-bis(4-nitrophenoxy) benzene was 14.1 g(40.1 mmol),and the volume fraction of hydrazine hydrate was 20 mL,selected the catalyst FeCl3.6H2O’s mass was 1.00 g,and active carbon’s mass was 2.50 g,and control reaction temperature of added the hydrazine hydrate was 70 ℃,after added finish,the reaction mixture was agitated and maintained at the refluence temperature,the yield of 1,3-bis(4-aminophenoxy) benzene was about 60%(according to the 1,3-bis(4-nitrophenoxy) benzene).
