| Abstract: | On the basis of the model for hard-sphere molecules and weak molecular attraction,the equation of state(CS-vdW) for molecular aggregation was developed by using molecular thermodynamic method in this paper Then,the pVT properties of liquids of high-carbon alkanes at saturation conditions were calculated by using the above equation of state The obtained results are in good agreement with the experimental data This shows that the proposed method may be used for engineering calculations The advantage of this method is simple and convenient in use It needs only a few known parameters,that is critical properties (p c,V c,T c) and molecular aggregation parameter(3C )for calculations |
