摘　　要：To obtain new functional aromatic polymer materiul. 3,3＇-biacenaphthene, which is used as macromolecule intermediate of,funcrion aromatic polymer material, was synthesized through the coupling reaction of acenaphthene catalyzing by ionic liquid （[bmim]CI/FeCl3） at mild reaction condition. Pure 3,3＇-biacenaphthene was obtained hy recrystalling and column chromatography from the reaction mixture and was determined by GC/MS, SHNMR arid FTIR analysis. The influence of various reaction conditions on the yield of 3,3＇-biacenaphthene were studied by GC analysis. The result shows that the optimun synthesis conditions of the coupling reaction are, as following： the molar ratio of FeCl3 to [BmimlCl being 3, the mole ratio of FeCl3 in [Bmim]Cl/FeCl3 to acenaphthene being 4. the reaction temperamre being 20 ℃ the reaction time being 4h and the solvent of the reaction system being PhNO2 Under those conditions, the yield of the 3.3＇-biacenaphthene will be 48.71% and selectivity, of that will be 78.56 %. Farther more, [bmim]Cl/FeCl3 has no pollution to environments and can be reused.To obtain new functional aromatic polymer material, 3,3’-biacenaphthene, which is used as macromolecule intermediate of function aromatic polymer material, was synthesized through the coupling reaction of acenaphthene catalyzing by ionic liquid ([bmim]Cl/FeCl3) at mild reaction condition. Pure 3,3’-biacenaphthene was obtained by recrystalling and column chromatography from the reaction mixture and was determined by GC/MS, 1HNMR and FTIR analysis. The influence of various reaction conditions on the yield of 3,3’-biacenaphthene were studied by GC analysis. The result shows that the optimum synthesis conditions of the coupling reaction are as following: the molar ratio of FeCl3 to [Bmim]Cl being 3, the mole ratio of FeCl3 in [Bmim]Cl/FeCl3 to acenaphthene being 4, the reaction temperature being 20 ℃, the reaction time being 4h and the solvent of the reaction system being PhNO2. Under those conditions, the yield of the 3,3’-biacenaphthene will be 48.71 % and selectivity of that will be 78.56 %. Further more, [bmim]Cl/FeCl3 has no pollution to environments and can be reused.
