abstract The interest in phase equilibrium and thermophysical properties of mixtures containing long chain hydrocarbons is increasing. Despite the industrial interest of these systems, the available experimental data are scarce, while new models are required. Corresponding States Theory has been used with success for the estimation of properties of pure components and mixtures of small molecules. This work shows how this theory can be extended to the evaluation of liquid density, vapour pressure and viscosity of long chain molecules in a broad temperature range, based on information of lower members of the same homologous series. Results for the n-alkane series showed that this new model is able to predict liquid density, vapour pressure and viscosity with percent average absolute deviations of 0.44, 0.52, and 3.15%, respectively.
