Positive Electron Impact and Chemical Ionization Mass Spectra of Some Nitramine Nitrates

Article abstract of DOI:10.1002/oms.1210241105

The positive electron impact (EI) and isobutane chemical ionization (CI) mass spectra of six nitramine nitrates were studied with the aid of some accurate mass measurements.In the EI spectra, β fission relative to both the nitramine and nitrate ester is important.In the CI spectra a major ion occurs at ⁺ and was found to be mainly due to ⁺.All of the compounds except N-(2 hydroxyethyl)-N-(2',4',6'-trinitrophenyl)nitramine nitrate gave an ⁺ ion.The ⁺ ion in the isobutane CI mass spectra of tetryl is also due to ⁺.
