Abstract
The ozonation of ethylene glycol and diethylene glycol mono-n-octyleth er (models of non-ionic surfactants) has been performed in aqueous sol ution at pH 4 and pH 9.5. The experiments at acidic pH show that the m ethylene groups adjacent to the ethereal oxygens are transformed into carbonyl groups. At alkaline pH the aliphatic chain is cleaved. Kineti c experiments allow to suggest a reaction mechanism. (C) 1997 Elsevier Science Ltd.
