Volatility of blended fuel of endothermic hydrocarbon fuel and triethylamine

Bubble-point vapor pressures and equilibrium temperatures for the mixtures of a refined kerosene based endothermic hydrocarbon fuel (EHF) and triethylamine (TEA) with different mass fractions were measured by comparative ebulliometry with inclined ebulliometers. Experimental data of vapor pressures and equilibrium temperatures were correlated by the Antoine equation. The bubble-point lines of pressure versus composition at different temperatures and temperature versus composition at different pressures were obtained. It is found that the pseudo‐binary systems of EHF+TEA have positive deviations from Raoult's law, and the blended fuels have higher volatility than pure EHF.
