Notes:
The 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.
