This study presents vapor pressure data for narrow boiling range fractions, viewed as pseudocomponents, prepared by rectification from a wide Kukersite oil shale retort oil gasoline fraction, a straight-run fraction with a boiling range from about 40 to about 200 °C. This technical gasoline fraction was produced in a commercial solid heat carrier retort. Vapor pressures were measured according to the ASTM D6378 standard with a commercial ERAVAP vapor pressure tester using a vapor-liquid ratio of 4:1. The vapor pressure curves were derived by fitting the experimental data using the integrated form of the Clausius-Clapeyron equation. From this equation heats of vaporization and atmospheric boiling points were calculated. The suitability of three easy-to-use conventional oil vapor pressure correlations for predicting the vapor pressure of narrow boiling range fractions of Kukersite oil shale retort oil gasoline was evaluated.
