The results of measurements of saturated liquid densities using a high-pressure stainless steel pycnometer system over a wide variation of temperature from 298.15 to 473.15 K are presented for benzene, cyclohexane, and hexane. Experimental densities were compared with those predicted by the Spencer-Danner-modified Rackett equation (SDR) and the Hankinson-Brobst-Thompson correlation (HBT). The SDR showed an average deviation of 0.22% while the HBT predicted the densities of the three organic solvents with an average deviation of 0.28%. The data obtained have also been compared with the available data reported in the literature.
