为合成新型功能高分子中间体，分别研究了在AlCl3，FeCl3，ZnCl2等无机盐和[Bmim]Cl／FeCl3离子液体催化作用下，苊在温和条件常温常压下的偶联反应．经GC／MS分析发现生成了3，3＇-联苊．用GC法考察了不同反应条件对3，3’-联苊产率的影响，得到了各催化剂作用的优化反应条件．结果表明，上述几种催化剂中，[Bmim]Cl／FeCl3离子液体对苊的偶联反应催化效果最好，在该催化剂作用的优化反应条件下，3，3’-联苊产率为48．71％，选择性78．56％，且[Bmim]Cl／FeCl3离子液体对环境无污染，并可循环使用．通过重结晶、层析等方法得到了功能高分子中间体3，3‘-联苊纯品，并用GC／MS，FTIR和^1H NMR等分析测试手段鉴定了其结构．

英文摘要：

To obtain new functional aromatic polymer intermediates, the coupling reaction of acenaphthene catalyzed by inorganic salts, such as AlCl3, FeCl3, ZnCl2 and ionic liquid（ [ Bmim] Cl / FeCl3 ） , was investigated at room temperature and ambient atmosphere. The 3,3＇- biacenaphthene was determined by GC/MS analysis and the effects of various reaction conditions were studied by GC analysis. The results showed that [ Bmim] Cl / FeCl3 was the optimum catalyst, and under the optimum synthesis condition, the yield of 3,3＇- biacenaphthene is 48.7% and selectivity is 78.56%. Furthermore, [ Bmim ] Cl / FeCl3 is environmentally benign, and can be reused at least 6 times without loss of any activity. 3,3＇- biacenaphthenys, which may be used as an intermediate of function aromatic polymer materials, was prepared by recrystalling and chromatography the reaction mixture. The structure of 3,3＇- biacenaphthene was identified by GC, GC/MS, FTIR and ^1H NMR analyses.
