Abstract

Sample ion/sample molecule reactions often occur under high pressure CI and low pressure FT/ICR conditions with large sample size of polar compounds, and are useful in obtaining molecular weight information. In this paper, FT/ICR/MS was used to study ion-molecule reactions of C2H5O+ ions made from three different sources. The ions were reacted with PEG oligomers so as to differentiate among the structures of the m/z 45 ions. Time dependence studies of product ions from these reactions were also made. C2H5O+ ions produced from ethylene oxide and from PEG oligomers reacted essentially by proton transfer and gave similar spectra which are different from those of C2H5O+ ions made from dimethyl ether. The suggested structure could be any of II â€“IV. The reactions of the isomeric C2H5O+ ions from dimethyl ether with PEG oligomers show a methyl cation transfer as a product ion, (M+13)+ ions, suggesting a CH3-O=CH2+ structure as shown in structure I. The two isomers reacted mostly by proton transfer with minor amounts of methyl cation transfer which points to structure IX. The C3H7O+ ions from the ion-molecule reaction of acetone and vinyl methyl ether react mostly by proton transfer could have the structure of X or XI.
