Abstract

A second virial coefficient correlation suitable for two different temperatures ranges, (T*)^-2£180 and (T*)^-2>180, where T* is RT/DH_vap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from T_tp to T_c and up to high pressures. The latent heat of vaporization and density at the triple point are the only two parameters that are needed in these calculations. The results indicate that the liquid densities of liquid mixtures with quite different acentric factors can be predicted to within about 5%.
