应用EI质谱和联动扫描技术研究了13个有机磷杂环化合物,讨论了主要离子的形成过程,分子离子在EI条件下的各种重排反应和取代基对不同解离反应产物离子相对强度的影响。
Thirteen organophosphorus heterocyclic compounds were studied by EI mass spectrometry and scanning electron microscopy. The formation of main ions, the rearrangement reaction of molecular ions under EI and the relative intensities of substituents on dissociation products influences.
