| 摘 要： | 本文用自由基捕捉剂亚硝基叔丁烷(MNP),2,3,5,6-四甲基亚硝基苯(ND)及苯亚甲基叔丁基氮氧化物(PBN)与ESR相结合的方法研究了二苯基汞(DPM)在胶束中光解产生的活泼自由基。结果表明:(1)在含有表面活性剂的水体系中,DPM光解产生苯基自由、基并可被MNP捕获;(2)在含有表面活性剂的某些有机溶剂RH中,DPM光解不仅产生自由基C_6H_5,并且随溶剂不同,C_6H_5可夺取溶剂RH上的活泼氢而产生次级自由基R,它们均能被ND或PBN捕获。

| Abstract: | The active free radicals formed during the photolysis of diphenyl-mercury (DPM) in micellar solution have been examined by ESRspectro-scopy and spin trapping technique. The results showed that:1. In aqueous media containing surfactants, phenyl radical could be formed during the photolysis of DPM and trapped by methyl nitrosopro-pane (MNP).2. In some organic solvent RH containing surfactants, not only the primary radical C6H5 ,but also the secondary radicals R were produced during the photolysis of DPM. |
