摘要
合成并表征了3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]NTf_2,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(NTf_2)_2·2H_2O),对H_2O_2/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H_2O_2/CEES摩尔比、H_2O_2浓度、反应温度、时间、离子液体再生次数对H_2O_2/[EMIm]NTf_2/Fe^(2+)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H_2O_2/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.
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（ NTf_2）_2·2H_2O）were synthesized and characterized. Then the decontamination performances of HD simulant CEES in H_2O_2/ ILs were studied. The influential factors,including H_2O_2/ CEES molar ratio,H_2O_2 concentration,temperature,reaction time and ILs recycling were investigated using HPLC to obtain the optimal conditions for the degradation of CEES in H_2O_2/[EMIm]NTf_2/ Fe^（2＋）. 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 might be an outstanding option in low-temperature decontamination of CEES and behaved many advantages such as lower H_2O_2/ CEES molar ratio,rapider reaction rate and favorable reaction selectivity.
