A modified perturbed hard-sphere-chain equation of state for pure halogenated organic compounds

Our previously reported modified perturbed hard-sphere-chain equation of state has been employed to calculate the PVT properties of pure halogenated organic compounds. Knowing the critical constants of fluids as well as one adjustable substance-dependent parameter as input data is sufficient for this purpose. We have tested the proposed equation of state against the experimental data for a large number of pure halogenated organic compounds both in saturation and compressed states. Comparison of the calculated results with the experimental data shows that from 734 data points for saturation state and 1450 data points for compressed state the average absolute deviations in calculated densities are 0.51 and 0.61%, respectively.
