ABSTRACT

The present work shows a successful extension of previous studies to molecular liquids for which the second virial coefficients are not known. Recent advances in the statistical mechanical theory of equilibrium fluids can be used to obtain an equation of state (EOS) for compressed normal liquids and molten alkali metals. Three temperature-dependent quantities are needed to use the EOS: the second virial coefficient, B(T), an effective van der Waals covolume, b(T), and a scaling factor, α(T). The second virial coefficients are calculated from a correlation that uses the surface tension, γtr, and the liquid density at the triple point. Calculation of α(T) and b(T) follows by scaling. Thus, thermodynamic consistency is achieved by use of two scaling parameters (γtr, ρtr). The correlations embrace the temperature range Ttr More... »

Three temperature-dependent quantities are needed to use the EOS: the second virial coefficient, B(T), an effective van der Waals covolume, b(T), and a scaling factor, α(T). The second virial coefficients are calculated from a correlation that uses the surface tension, γtr, and the liquid density at the triple point. Calculation of α(T) and b(T) follows by scaling. Thus, thermodynamic consistency is achieved by use of two scaling parameters (γtr, ρtr). The correlations embrace the temperature range Ttr<T<Tc and can be used in a predictive mode. The remaining constant parameter is best found empirically from ρtr data for pure dense liquids. The equation of state is tested on 42 liquid mixtures The results indicate that the liquid density at any pressure and temperature can be predicted within about 5%, over the range from Ttr to Tc.
