摘　　要：以N-甲基咪唑、吡啶、1,4-丁烷磺内酯、对甲苯磺酸及硫酸为主要原料,经两步反应合成了4种酸功能化离子液体[MIM-BS][TsO](IL1)、[MIM-BS][HSO4](IL2)、[PY-BS][TsO](IL3)和[PY-BS][HSO4](IL4),其结构和性能经~1H NMR,IR和TGA表征。以[MIM-BS][TsO]为催化剂,催化2-(4-叔丁基苯甲酰基)苯甲酸(BB酸)合成2-叔丁基蒽醌,并对反应条件进行了优化。结果表明:IL1 0.4 g,n(IL)/n(BB酸)=0.5,于120℃反应9 h,2-叔丁基蒽醌产率最高达90%,离子液体循环使用5次后催化活性无明显降低。Four acid functional ionic liquids, [ MIM-BS ] [ TsO ] （ILl）, [ MIM-BS] [ HSO4 ] （IL2）, [ PY-BS ] [ TsO ] （IL3） and [ PY-BS ] [ HSO4 ] （IIA） were synthesized using N-methylimidazole, pyr- idine, 1,4-butane sultone, p-toluene sulfonic and H2SO4 as raw materials. The structures were charac- terized by ^1 H NMR, IR and TGA. 2-Tert-butylanthraquinone was synthesized from 2- （4-tertbutyl ben- zoyl） benzoic acid（BB acid） using [MIM-BS] [ TsO] as catalyst. The reaction conditions were opti- mized. The results showed that the yield of 2-tert-butyl anthraquinone reach 90% when n （IL）/n （BB） was 0.5, ILl was 0.4 g, reaction at 120 ~C for 9 h. Moreover, the catalytic activity of [ MIM- BS ] [ TsO ] exhibited no obvious decrease after being reused for five times.
