New, rapid analytical techniques based on cyclic voltammetry are being developed to determine the hydroperoxide contents and the thermal and thermaloxidation stabilities of different type jet fuels (straight run, hydrotreated, JP-4, and JP-5). The techniques are performed at room temperature, use less than 1 mL of fuel, and use common solvents containing different electrolytes or reactive compounds. The cyclic voltammetric techniques were used to quantify the natural antioxidants, easily oxidizable compounds, and hydroperoxides present in different type fuels. Mathematical relationships were then developed to evaluate the potential of the voltammetric results to predict the thermal and oxidative stabilities of the jet fuels determined by high temperature oxidation and thermal stability tests.
