The use of carbon dioxide at its near critical conditions for the extraction of oxidation products from mineral oils is described. Paraffinic and naphthenic additive-free base stock oils with acid numbers exceeding those specified by the manufacturers were subjected to carbon dioxide extraction. The original specified limit on acidity was achieved using the above technique while retaining the required characteristics of the mineral oils studied. Infrared spectroscopic results confirmed the effectiveness of the removal of the oxidation products by the above technique. 10 references, 4 figures, 1 table.
