title: Ozonolysis of organic compounds and mixtures in solution. Part I: Oleic, maleic, nonanoic and benzoic acids.
abstract: In this paper, infrared spectroscopic and mass spectrometric studies of the ozonolysis of some simple proxies of precursors to organic materials found in atmospheric aerosols is reported. Oleic and maleic acids are used as proxies of reactive material, containing unsaturation which is amenable to ozonolysis. Nonanoic acid and benzoic acid are utilised as co-reactants which, although not likely to undergo direct ozonolysis themselves, are potential reaction partners to the Criegee radical intermediates formed from oleic and maleic acid ozonolysis. The precursor species are studied as single components in solution, followed by co-reaction studies. The products of the ozonolysis are followed by mass spectrometry and infrared spectroscopy. The product distributions from oleic and maleic acid are broadly in agreement with those observed in other studies. In the co-reaction studies, new evidence for cross-reaction products is obtained. Furthermore, the nature of some of the products does not fully comply with the widely accepted Ziemann scheme.
