Abstract

This paper reports the results of measurements of the densities of binary mixtures of cyclohexane with hexane using a high pressure stainless steel pycnometer system at various temperatures between 298.15 K and 473.15 K. The results were compared with those predicted by the Hankinson-Brobst-Thomson correlation (HBT) and the Spencer and Danner modified Rackett equation (SDR). The HBT equation showed an average deviation of about 0.36% from the experimental results while the SDR equation showed a 0.15% average absolute deviation. The excess molar volumes, V^E, calculated from the density values have been found to change from positive to negative values with the increase of temperature.
