Application of nondestructive evaluations to the prediction of turbine fuel peroxidation potential. Final report, 5 August 1987-5 February 1988

After the theoretical and experimental baselines were established to determine the potential peroxide content of jet fuels, nondestructive methods of analyses were evaluated to augment the procedures. The use of proton nuclear magnetic resonance (NMR), ultraviolet (UV), and infrared (IR) spectroscopies were evaluated. UV and NMR did not respond to the trace-quantity compositional changes caused by autoxidation in the examined fuels. Direct detection and measurement of the primary autoxidation intermediates, that is, peroxides and hydroperoxides, were not feasible by the applied nondestructive analytical methods. Indications are that IR may be used for the detection and measurement of peroxide decomposition products such as alcohols and carbonyl compounds.
