"NL - Nizozemsko" . . . "We have carried out a selected ion flow tube, SIFT, study of the reactions of H3O+, NO+ and O2+. with the following six nitroalkanes: nitromethane, nitroethane, 1-nitropropane, 2-nitropropane, 1-nitrobutane and 2-methyl-2-nitropropane. The primary purpose of this work was to extend the kinetics database to allow these compounds, M, to be analysed in air by selected ion flow tube mass spectrometry, SIFT-MS. Some nitroalkanes are used as industrial solvents and some are component of agricultural agents that are known health hazards. The initial step in all the H3O+ reactions is exothermic proton transfer to produce MH+ ions, which are seen to be the only products for the two smallest nitroalkanes, but for the isomers of nitropropane and nitrobutane, fragmentation of the nascent MH+ ions occurs. NO+ reacts with the four smallest compounds via association resulting in NO+M product ions, whilst for the isomers of nitrobutane the C4H9+ hydrocarbon ion is produced." . .
