Abstract: An apparatus for measurement on vapor pressures of multicomponent system was constructed using an inclined ebulliometer with a pump like stirrer according to the principle of quasi static method. It was used to determine the vapor pressures at various temperatures of a series of base oils for endothermic hydrocarbon fuel. The relationship between vapor pressures and temperatures was correlated by Antoine equation. The vaporization enthalpies of these base oils were then calculated from Clausius Clapeyron equation. These results provide basis information for the study and performance of endothermic hydrocarbon fuel.
