| Abstract |
In order to prepare new functional macromolecule material, the coupling reaction of
acenaphthene catalyzed by [Bmim]Cl/FeCl3 ionic liquid was investigated under mild reaction
conditions and without any additional organic solvent. Pure 3,3’-biacenaphthene, which is used as
intermediate of function aromatic polymer material, 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 coupling reaction of acenaphthene were
studied by GC analysis and the optimum synthesis conditions of the reaction were obtain. Under
optimun conditions, the yield of 3,3’-biacenaphthene will be 63.5 % and selectivity of that will be
85.6 %. Further more, [Bmim]Cl/FeCl3 is environmentally benign catalyst and solvent and can be
reused. |
