A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap 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 Ttp to Tc 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%.
