Temperature dependence of the derived properties of mixtures containing chlorobenzene and aliphatic linear alkanes (C₆–C₁₂)

Abstract

This article reports experimental densities, refractive indices and speeds of sound of the binary mixtures chlorobenzene + (n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane or n-dodecane) and speeds of sound of the ternary mixtures chlorobenzene + n-hexane + (n-undecane or n-dodecane) at 298.15 K and atmospheric pressure, over the whole concentration range. The corresponding derived properties were computed from the experimental data. The results were fitted by means of the Redlich–Kister equation for binary mixtures and the Nagata equation for ternary mixtures. A set of estimation methods were applied, and an interpretation in terms of structure and length of molecular chain of the n-alkane molecules was made.
