Abstract

The mass spectra of C2 to C7 n-alkanals have been measured using a double focusing mass spectrometer. The various reaction mechanisms by which the fragment ions are formed have been elucidated and discussed. Two reactions, the β-cleavage with rearrangement and the y-cleavage reactions lead, respectively, to [C2H4O]+ and [C3H5O]+ ions with significant intensities in butyraldehyde and higher n-alkanals.

The electron energy distribution difference (EDD) method together with a computer programme have been used for evaluating ionization efficiency curves for the molecular ions. The ionization potentials obtained by this method show good agreement with those obtained from other electron impact and photoionization experiments.
