Abstract: | To obtain new functional aromatic polymer material. 3.3'-biacenophthene. which is used as macrotnolecule 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 optimun 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. |
