摘要/Abstract

摘要： 研究了碘杂环化合物质谱行为和电子碰撞诱导裂解途径.结果表明:3,6-二硝基-二苯并碘六环卤化物(Ⅰ、Ⅱ、Ⅲ)和3,6-二硝基-9-酮-二苯并碘六环卤化物(Ⅳ、Ⅴ、Ⅵ)的EI质谱是样品在仪器内热分解产物的混合质谱;吸附在样品上的溶剂甲酸参与了后者的热分解过程;电子碰撞诱导裂解产生的碎片离子2-卤-2′-碘-4,4′-二硝基-二苯酮(Ⅳ′、V′、Ⅵ′)是化合物Ⅳ、V、Ⅵ的主要热分解产物.

Abstract: The experimental data show that the EImass spectra of 3,6-dinitro-dibenzopyriodonium halides (X = Cl, Br, I) and 3,6-dinitro-9-one-diben-zopyrdonium halides (X = Cl, Br, I) are the mixed mass spectra of their thermolysis products produced inside the instrument. The adsorbed solvent, formic acid, in the samples (Ⅳ-Ⅵ)takes part the thermolysis process. By the electron collision induced fragmentation, one can easily identify 2-halo-2' -iodo-4, 4' -dinitro-dibenzoketone, the main thermolysis product of 3,6-dinitro-9-one-dibenzopyriodonium halides (X = Cl, Br, I).
