Abstract

This paper reports the results of measurements of the densities for benzene + hexane using a highpressure stainless steel pycnometer system at various temperatures between 298.15 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 0.74% from the experimental results while the SDR equation showed a 0.20% average absolute deviation. The excess molar volumes, V^E, calculated from the density values have been found to be positive for all the concentrations and temperatures considered.
