Abstract
The reactions of CHO+ ions derived from acetaldehyde source molecules on propylene have been studied using an in‐line tandem mass spectrometer. Rate constants for the formation of propyl ions and for the unimolecular dissociation of propyl ions into C2H3+(+CH4) and C3H5+(+H2) as a function of ion translational energy were estimated from experimental data and reaction parameters. Comparison of the results with rates of decomposition of excited propyl ions calculated from the quasiequilibrium theory of mass spectra lead to the conclusion that the initial interaction of CHO+ with propylene takes place via proton stripping rather than complex formation.Keywords
