英文摘要：

The reactions of imidazolium-based ionic liquids having different substituent groups on the ring with hydrated electrons （eaq-）,hydroxyl radicals （·OH）,and sulfate anion radicals （SO4·-） were investigated using nanosecond pulse radiolysis techniques.The spectra of these ionic liquids on reaction with eaq-all exhibited a similar peak at about 320 nm,and a typical peak for eaq-in aqueous ionic liquid solutions.The reaction rate constants for 1,3-disubstituted imidazolium-based ionic liquid hexafluorophosphates （BMIPF 6） with eaq-were deduced to be 10 10 L mol-1s-1,however the values were lower for trisubstituted ionic liquids.For example,the rate constant for 1-butyl-2,3-dimethylimidazolium tetrafluoroborate （BMMIBF 4） was 5.5×10 9 L mol-1s-1.Imidazolium-based ionic liquids reacted with hydroxyl radicals via adducts to produce a mixture of isomeric OH adducts,and the pk a value of the OH adducts was deduced to be 8.4±0.4 for 1-butyl-3-methylimdazolium tetrafluoroborate （BMIBF 4）.Moreover,imidazolium cations were also oxidized by SO4·-to produce bivalent cation radicals,which exhibit a peak at 320 nm,and these rate constants are of the same order of magnitude,i.e.,10 9 L mol-1s-1,except that for 1-（2-hydroxyethyl）-3-methylimdazolium tetrafluoroborate with SO4·-（k=2.8×10 8 L mol-1 s-1）.Theoretical calculations were carried out to estimate the structures of the products of reduction by eaq- and the results were related to the experimental data.
