在无有机溶剂和卤素的条件下,以钨酸/酸性离子液体为催化体系、质量分数30%的双氧水为氧化剂,催化氧化环己烯合成己二酸.当n（环己烯）∶n（钨酸）∶n（N-甲基咪唑硫酸氢盐（[HMIM]HSO4））∶n（双氧水）=50∶1∶5∶220（离子液体用量为10 mmol）时回流反应7.5 h,己二酸的分离产率可达90.5%.且离子液体廉价易制备、环境友好、可重复使用.
在無有機溶劑和滷素的條件下,以鎢痠/痠性離子液體為催化體繫、質量分數30%的雙氧水為氧化劑,催化氧化環己烯閤成己二痠.噹n（環己烯）∶n（鎢痠）∶n（N-甲基咪唑硫痠氫鹽（[HMIM]HSO4））∶n（雙氧水）=50∶1∶5∶220（離子液體用量為10 mmol）時迴流反應7.5 h,己二痠的分離產率可達90.5%.且離子液體廉價易製備、環境友好、可重複使用.

Without any organic solvent and halide,oxidation of cyclohexene to adipic acid with aqueous 30% hydrogen peroxide catalyzed by tungstic acid/acidic ionic liquids was carried out.When the molar ratio of cyclohexene,tungstic acid,N-Methylimidazolium hydrosulfate（HSO4） and hydrogen peroxide was 50∶1∶5∶220（HSO4,10 mmol）,the isolated yield of adipic acid could reach 90.5 % for 7.5 h under reflux temperature.Such yield was same or better than that obtained from the present research,the catalyst was cheap,easily prepared,and environment-friendly can be recycled easily with no loss of the activity.
