Abstract
Bis(4 aminophenoxy)benzonitrile(BAPB) was synthesized by reaction of 2,6 dichlorobenzonitrile and 4 aminophenol using anhydrous sodium carbonate as acid acceptor and N,N dimethylacetamide and toluene as solvent.The influences of the kind of acid acceptors and reaction time on the yield of the product were investigated.The results showed that the product with 64.5% yield was obtained when the mole ratio between 2,6 dichlorobenzonitrile and 4 aminophenol was 1∶2 and reaction was carried out at 120 ℃ for 36 h.
