AlCl3催化苊与硝基苯制备功能高分子中间体

为制备更多新型功能高分子中间体，研究了高活性lewis酸AlCl3催化作用下，苊与硝基苯在温和条件常温常压下的反应．GC／MS分析发现生成了N-苯基氨基苊烯、N-苯基氨基苊、联苊-苊烯和联苊等产物．GC考察了不同反应条件对苊转化率和产物选择性的影响，时间对苊转化率影响不大，N-苯基氨基苊的选择性随着时间增加而增大；随着AlCl3用量的增加，苊转化率和N-苯基氨基苊的选择性随之增加；AlCl3与苊的摩尔比为1．2和2．4时，产物中联苊和N-苯基氨基苊的选择性分别达到77．6％和90．2％．对不同反应条件下的反应产物，通过重结晶获得了多环功能高分子中间体联苊和染料、医药中间体5-（N-苯基）氨基苊两种主产物的纯品，用GC／MS、FT—IR、UV和^1H NMR等分析测试手段鉴定了其结构．

Preparation intermediate of functional polymer material by AlCl3 catalyzing acenaphthene with nitrobenzene

To obtain new functional aromatic polymer material,the reaction of acenaphthene with nitrobenzene under high active catalyst of AlCl_3 was investigated at room temperature and ambient atmosphere.N-phenyl aminoacenaphthylene,N-phenyl aminoacenaphthene,acenaphthylacenaphthene,and biacenaphthenyls were determined by GC/MS analysis.The effects of various reaction conditions were studied by GC analysis.Reaction time has slight effect on the conversion of acenaphthene.The selectivity of N-phenyl aminoacenaphthene increases with reaction time.Biacenaphthenyls or N-phenyl aminoacenaphthene is in the majority,77.6% or 90.2% when the molar ratio of AlCl_3 to acenaphthene is 1.2 and 2.4 respectively.Pure biacenaphthenyls and 5-(N-phe-nyl) aminoacenaphthene,which may be used as intermediate of functional aromatic polymer material,were prepared by recrystalling the reaction mixture obtained under different reaction conditions.The structures of these compounds were identified by GC/MS,FTIR UV and ~1H NMR analyses.
