Electron ionization and gas-phase ion molecule reactions of methylcyclohexane
C. Q. Jiao, Karl Irikura, S, F. Adams, A Garscadden
Absolute cross sections for electron impact ionization of methylcyclohexane (MCH, C7H14) are measured as a function of the electron energy in a range of 10 to 200 eV. The reactions between selected hydrocarbon ions with MCH, mainly via hydride transfer, charge transfer and H2 transfer mechanisms, are studied. Absolute rate constants are reported, and the connection between the reactivities and the thermochemical data of the reactions is discussed. The binary encounter Bethe method is applied to MCH to provide a theoretical comparison to the sum of the measured ionization cross sections.
