An increasing number of problems are being experienced with the currently available jet fuels. These fuels can form solids, increase in peroxide number, corrosiveness, and develop color and high viscosity when stored. Antioxidants (hindered phenols) have been generally used to overcome storage instability in these fuels. The objectives of this project are: (1) develop methods for accurately monitoring antioxidant depletion and peroxide formation in JP-5 fuels; and (2) assess changes in chemical composition of fuels upon aging. The following two techniques were developed for determination of antioxidant concentration in jet fuels: (1) reverse-phase high performance liquid chromatography used in conjunction with an electrochemical detector; and (2) gas chromatography/mass spectroscopy with selective ion monitoring. Concentration of two commercially available antioxidants (AO-29 and AO-33 at 12 and 24 ppM levels in a JP-5 fuel) was monitored using these techniques. Jet fuel samples with and without antioxidants are currently being aged in an oven at 60 C. Samples are being withdrawn at regular intervals. The samples collected for up to 12 weeks of storage did not indicate any sign of instability; however, the peroxide number of the fuel sample without antioxidants added increased significantly with fuel aging. 2 refs., 5 figs., 2 tabs.
