Abstract
 Proton transfer reactions and ion-molecule reactions of bifunctional ethanes of H2NCH2CH2NH2, H2NCH2CH2OH, and HOCH2CH2OH were studied using Fourier transform mass spectrometry (FTMS). The rate constants for proton transfer reactions between the fragment ions and neutral molecules were obtained from the temporal variation of the ion abundances. The rate constants were consistent with the heats of reaction. The fastest proton transfer reactions were the reactions of CH2N+, CHO+, and CH3O+ for H2NCH2CH2NH2, H2NCH2CH2OH, and HOCH2CH2OH, respectively. The [M+13]+ ion was formed by the ion-molecule reaction between H2C=NH2 + or H2C=OH+ and the neutral molecule. The major product ions generated from the ionmolecule reactions between the protonated molecule and neutral molecule were [2M+H]+, [M+27]+, and [M+15]+.
