We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications to the classical measurement provide for (1) a composition explicit data channel for each distillate fraction (for both qualitative and quantitative analysis), (2) temperature measurements that are true thermodynamic state points, (3) consistency with a century of historical data, (4) an assessment of the energy content of each distillate fraction, (5) trace chemical analysis of each distillate fraction, (6) corrosivity assessment of each distillate fraction. This latter modification is achieved with a new sampling approach that allows precise qualitative as well as quantitative analyses of each fraction, on the fly. We have applied the new method to the measurement of rocket propellant, gasoline and jet fuels. In this paper we present the application of the technique to representative batches of the military aviation fuel JP-8, and also to a coal derived fuel developed as a potential substitute, JP-900. We present not only the distillation curves but also a chemical characterization of each fraction, and discuss the contrasts between the two fluids.
