摘要
Vapour-phase thermodynamic properties of methanol and ethanol have been fitted to a cubic equation of state with two temperature-dependent parameters. The parameter a(T) is fitted to the second virial coefficient, and the parameter c(T) is fitted to saturated vapour densities. The equation gives good values of thermodynamic properties up to 0.98T(c) and at pressures up to p(c). Vapour pressures are accurate to ca. 1%, vapour densities to 2% and enthalpy increments to 1%.
