Excess molar volumes of the ternary mixtures chlorobenzeneY n-HexaneYlinear aliphatic alkane (C7-C8) at 298.15K

摘要

This article reports experimental values of densities of the ternary mixtures Chlorobenzene + n-hexane + (n-heptane or n-octane) at 298.15K and atmospheric pressure, over the whole concentration range. The corresponding excess molar volumes were computed from the experimental data. The results were fitted by means of the Nagata equation, such parameters being gathered. Simple mixing rules were applied into cubic equations of state (EOS) of two parameters for prediction, only a qualitative agreement between the experimental and theoretical values both in magnitude and sign being obtained, due to the high non-ideal trend of mixtures.
