Under γ-irradiation, aqueous solutions of ethylene glycol containing hydrogen peroxide form acetaldehyde as a major product via a free-radical chain rearrangement. The yield of acetaldehyde is essentially unchanged when hydrogen peroxide is replaced by N 2 O or HClO 4 . A mechanism is proposed in which the glycol radical, ĊOHCH 2 OH, rearranges to the acetaldehyde precursor, ĊH 2 CHO, followed by the hydrogen atom transfer reaction;[Formula: see text]thus propagating a chain reaction. 2 The rearrangement is also induced by the photo-dissociation of H 2 O 2 in aqueous solutions of ethylene glycol.
