Text of Note

Densities of the pure compounds of benzene, cyclohexane and n-hexane as well as the densities of their binary and ternary mixtures have been measured. The experimental data were compared with predictions by two renowned correlations; the Hankinson-Brobst-Thompson correlation (HBT) and the Spencer-Danner modified Rackett (SDR) equation. The two correlations appear to be quite satisfactory in predicting the saturated liquid density of the pure and liquid mixtures considered. The excess molar volumes, VE for the binary liquid mixtures of benzene and cyclohexane, benzene and n-hexane, and cyclohexane and n-hexane from ambient to 200C, were calculated from the density data. Values of the VE for the three systems have been correlated, first as function of concentration using a 3-constant Redlich-Kister expansion, and second, as a function of temperature by expressing the coefficients in the Redlich-Kister expansion in terms of temperature. Values of VE have been found to be positive for benzene and cyclohexane and benzene and n-hexane mixtures. For cyclohexane and n-hexane, the values of VE have been found to change from positive to negative with increasing temperature. (Abstract shortened by UMI.)
