采用选择性好、催化效率高的氯代1-乙基-3-甲基咪唑-三氯化铝（[Emim]Cl-AlCl3）离子液体催化蒽与草酰氯的Friedel—Craft酰基化反应，合成了重要的精细化工产品及功能高分子中间体1，2-蒽乙二酮．用Gc法考察了不同反应条件对1，2-蒽乙二酮产率和选择性的影响，结果表明当AlCl3在[Emim]Cl-AlCl3离子液体中的摩尔分数为0．67，离子液体与蒽的摩尔比为2，草酰氯与蒽摩尔比为2，反应温度为40℃，反应时间6h时，1，2-蒽乙二酮产率可达91．6％，选择性达98．5％．且[Emim]Cl／AlCl3离子液体对环境污染小，并可循环使用．采用萃取、重结晶等方法得到了1，2-蒽乙二酮纯品，通过熔点测定，GC，GC／MS，FFIR和^1H NMR对该产物进行了定性和定量分析．

英文摘要：

The Friedel-Crafl acylation of anthracene with oxalyl chloride catalysed by [ Emim ] Cl - AlCl3 ionic liquid to synthesize 1,2 -aeeanthrylenedione, which was used as important fine chemical and functional macromolecule intermediate, was studied. The effects of various reaction conditions on the yield and selectivity of 1,2 - aceanthrylenedione were studied by GC analysis. The results show that the suitable synthesis conditions of the aeylation reaction are as follows ： the molar fraction of AlCl3 in [ Emim ] Cl - AlCl3 is 0.67, the mole ratio of [ Emim ] Cl - AlCl3 to anthracene is 2, the mole ratio of oxalyl chloride to anthracene is 2, the reaction temperature is 40 ℃ and the reaction time is 6 h. Under those conditions, the yield of 1,2- aceanthrylenedione is 91.6 % and the selectivity towards 1,2 -aceanthrylenedione is 98.5 %. Furthermore, [ Emim] Cl - AlCl3 has little pollution to environment and can be reused. Pure 1, 2 - aceanthrylenedione was prepared by extraction and recrystalling and the structure of 1,2 - aceanthrylenedione was identified by measuration of melting point, GC/MS, FTIR and ^1H NMR analyses.
