中文摘要：

研究了在氯代1-甲基-3-丁基咪唑（[Bmim]Cl-AlCl3）离子液体室温催化下，多环芳烃蒽与2-氯丙烷的Friedel-Crafts烷基化反应．GC／MS分析表明反应生成了精细化工中间体2-异丙蒽；用GC考察了不同反应条件对2-异丙蒽收率和选择性的影响，AlCl3在[Bmim]Cl-AlCl3离子液体中的物质的量比为0．67，m（[Bmim]Cl-AlCl3）：m（蒽）=8：1，n（2-氯丙烷）：n（蒽）=1．5：1，反应温度30℃，反应时间4h时，2-异丙蒽的收率和选择性最高，分别为69．2％和77．1％．[Bmim]Cl-AlCl3离子液体对环境无污染，且可循环使用．经萃取、重结晶等方法得到2-丙蒽纯品，并通过GC，GC／MS，FTIR和1HNMR对反应产物进行了定性和定量测试．

英文摘要：

To obtain novel fine chemicals, [ Bmim ]Cl-AlCl3（ [ Bmin ] ＋ = 1 - butyl - 3 - methylimidazolium cation） ionic liquid was used as catalyst in the Friedel - Crafts alkylation of anthracene with 2 - chloropropane. Fine chemical intermediate of 2 -isopropylanthracene was prepared and confirmed by GC/MS analysis. The influences of various reaction conditions on the yield and selectivity of 2 - isopropylanthracene were studied by GC analysis. The results show that the optimum conditions of the alkylation reaction are as follows ： reation temperature of 30℃ for 4 h while the molar fraction of A1CI3 in [ Bmim ] Cl-AlCl3 to be 0.67, m（ [ Bmim] Cl-AlCl3 ）： m（anthracene） = 8： 1, n（2 - chloropropane） ： n（ anthracene） = 1.5： 1. Under the optimum condition, the yield and selectivity of 2 -isopropylanthracene are 69.2 % and 77.1% , respectively. The present study shows that [ Bmim ] Cl-AlCl3 is not only a novel environmental-friendly catalyst and solvent but also can be reused. The structure of 2 - isopropylanthracene was identified by GC/MS, FTIR and 1H NMR analyses.
