AbstractThe ion–molecule reactions between protonated acetaldehyde and methanol were explored on a quadrupole, quistor, quadrupole tandem mass spectrometer. In addition to proton transfer to methanol and subsequent methanol ionmolecule chemistry, the protonated acetaldehyde–methanol adduct and methylated acetaldehyde could be detected. Experiments with labelled counterparts showed that the formation of methylated acetaldehyde corresponds to substitution of the oxygen‐bound hydrogen of protonated acetaldehyde by the methyl group of methanol. The reaction rates involved and H–D exchange rates were determined.
