Ion-molecule reactions of toluene with methyl ethyl ketone and isopropanol

Ton-molecule reactions in the toluene-methyl ethyl ketone and toluene-isopropanol systems are shown to proceed via proton transfer mechanism. The observed increase in rate constants for these reactions with increasing kinetic energy E-k is due to activation energy. A decrease in rate constants with increasing E-k was observed in association reactions between the methyl ethyl ketone molecules and the [M + 1](+) ions. The reaction of deuterium exchange between the C7D8+ ions and isopropanol molecules was discovered.
