Abstract
1. Naphthenic-aromatic hydrocarbons give a considerable reduction in the thermal-oxidative stability of hydrocarbon fuels and are the cause and source of insoluble resin and sediment formation at elevated temperatures. 2. The minimum amount of sediment is formed when the naphthenic-aromatic hydrocarbons under investigation are added to decalin, and the maximum amount when they are added to isoalkanes or cyclanes with long side chains. 3. Oxidation of the naphthenic-aromatic hydrocarbons takes place at the naphthenic ring, which is subsequently ruptured with the formation of ketones. Rupture of the naphthenic ring in acenaphthene takes place at a C-C bond immediately adjoining either aromatic ring, and in tetralin between the first and second carbon atoms. 4. The naphthenic-aromatic hydrocarbons are the primary participants in solid-phase formation in the oxidation of hydrocarbon mixtures; however, the composition of the sediments also includes products of intensive oxidative polymerization and condensation of these hydrocarbons with alkanes and cyclanes.
