Abstract : Gaseous ionic reactions have been observed for a series of oxygenated compounds in the source of a mass spectrometer at pressures up to a few tenths of a torr. The major produce ions were the solvated protons. Major differences in relative abundances were observed for the higher solvated protons which suggested differences in stability: no more than two molecules of dimethyl ether, acetaldehyde, or acetone will be strongly bound to a proton, but more highly solvated protons will be stable for methanol, formic acid, and water. There are general areas of agreement between ionic reactions in the gas phase and their macroscopic counterpart. Reactions of protonated molecule-ions were observed in methanol, acetaldehyde, and acetone which may be considered as elementary steps of some of the acid-catalyzed reactions which occur in solution. Proton transfer was observed from H3O+ to HCOOH and the decomposition path of lowest energy of HCOOH2+ is the one which gives H3O+ and CO. (Author)
