✦ Synopsis

Sulphoxides were identified in the aqueous phase of the Hot-Water Flotation Process (HWFP) for the separation of oil from tar sand. The ease of formation of these polar compounds is demonstrated. Sulphonic acids and carboxylic acids were also detected in the aqueous phase and a tentative mechanism for their formation from organic sulphides via sulphoxides is suggested. The relevance of our results to the chemistry of oil spills is discussed.
