| Popis: | Products of interaction between alkylhydrazines and ethyl-, allyl-, and phenylisothiocyanates are studied using mass spectrometry in the modes of electron impact ionization and matrix-assisted laser desorption/ionization in combination with gas and liquid chromatography. Conditions for the chromatographic separation of reaction mixtures and mass spectrometric identification of target compounds in real-time and delayed modes are optimized. The physicochemical characteristics of the sorption of thiosemicarbazides are determined. The decomposition and fragmentation of their metastable protonated molecules are studied. Schemes are proposed for the formation of fragmented and characteristic thiosemicarbazide ions in different modes of ionization. |
