Oil fractions which are resistant to weathering and represent large volumes of toxic waste comprise very complex mixtures including hydrocarbons and carboxylic acids. Since such fractions are unresolved by conventional methods of analysis including gas chromatography (GC), they are often referred to as Unresolved Complex Mixtures (UCMs) or ‘humps’. The acids therein are also often referred to as naphthenic acids (NAs), though they too are often unresolved and unidentified. A number of model UCM hydrocarbons and NAs have been proposed, including alkylcyclohexyltetralins and alkylcyclohexylalkanoic acids.
