| 中文摘要: |
| 合成并表征了三种不同烷基链长的1-烷基-3-甲基咪唑双三氟甲基磺酰亚胺（[CnMIm]NTf2，n=2、4、6）离子液体及金属催化剂双三氟甲基磺酰亚胺铁二水合物（Fe(NTf2)2•2H2O），对H2O2/离子液体消毒芥子气模拟剂2-氯乙基乙基硫醚（CEES）的能力进行了研究。通过HPLC考察了H2O2/CEES摩尔比、H2O2浓度、反应温度、时间、离子液体再生次数对H2O2/[EMIm]NTf2/Fe2+消毒CEES能力的影响，并采用GC-MS、CL对反应产物、活性氧物种及反应机制进行了分析。结果表明：基于离子液体的类Fenton体系消毒CEES时，具有H2O2/CEES摩尔比小、消毒速率快、低温消毒效果良好、离子液体可循环利用等的优点，在毒剂洗消领域具有极大的应用前景。 |
| 英文摘要: |
| A series of ionic liquids 1-n-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([CnMIm]NTf2, n=2, 4, 6) and metal catalyst Iron(II) Bis(trifluoromethylsulfonyl)amide hydrate (Fe(NTf2)2•2H2O) were synthesized and characterized. Then the decontamination performance of HD simulant CEES in H2O2/ILs were studied. The influential factors, including H2O2/CEES molar ratio, H2O2 concentration, temperature, reaction time and ILs recycling were investigated using HPLC to estimate the optimal conditions for the degradation of CEES in H2O2/[EMIm]NTf2/Fe2+. The products, active oxygen species and reaction mechanism were also analyzed by GC-MS and chemiluminescence (CL). These results showed that the Fenton-like system based ILs may be an outstanding option in low-temperature decontamination of CEES and behaved many advantages such as lower H2O2/CEES molar ratio, rapider reaction rate and favorable reaction selectivity. |
