Prediction of Halocarbon Liquid Densities by a Modified Hard Sphere-Desantis Equation of State
The present paper describes a general scheme for the prediction of halocarbon liquid state densities based on a modified hard sphere De Santis equation of state. It is shown that it is possible to estimate the density of pure liquids solely from the critical constants and relative molecular mass to better than 1.5% for T* < 0.9 and from saturation vapour pressures up to 20 MPa.
