Sa. Beg et al., DENSITIES AND EXCESS VOLUMES OF CYCLOHEXANE PLUS HEXANE BETWEEN 298.15 K AND 473.15 K, Fluid phase equilibria, 113(1-2), 1995, pp. 173-184
This paper reports the results of measurements of the densities of bin
ary mixtures of cyclohexane with hexane using a high pressure stainles
s steel pycnometer system at various temperatures between 298.15 K and
473.15 K. The results were compared with those predicted by the Hanki
nson-Brobst-Thomson correlation (HBT) and the Spencer and Danner modif
ied Rackett equation (SDR). The HBT equation showed an average deviati
on 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.
