Mass Spectra Electron Ionization of Tetraalkyl Pyrophosphates in the Mode of Registration of Positive Ions and Negative Ions of Resonance Electron Capture. Group Identification and Determination of the Number of Carbon Atoms in Alkyl Radicals of These Compounds

Abstract

he decomposition paths of tetraalkyl pyrophosphates under conditions of electron ionization in the mode of registration of positive ions correspond to the general pattern of fragmentation of phosphoric acids esters elucidated earlier by the authors. Electron ionization mass spectra in the mode of registration of negative ions by resonant electron capture are an effective means for extracting information on the number of carbon atoms in the alkyl radicals of tetraalkyl pyrophosphates and full esters of other phosphoric acids
