TL;DR: A modified statistical associating fluid theory with variable range version is presented using the family of m-n Mie potentials, and it is found to give a very accurate description of both vapor-liquid equilibria and compressed liquid bulk properties for long-chain n-alkanes.

TL;DR: Good agreement obtained is an indirect proof of the consistency of interfacial density profiles computed with the gradient theory for this mixture and confirms that the gradient Theory is suitable and reliable to describe the microstructure of complex fluid interfaces.

TL;DR: The model is able to reproduce accurately the complex behavior of the isobaric heat capacity of alcohols as, for instance, the maximum versus temperature in the compressed liquid region and in the case of 1-hexanol + n-hexane binary mixtures, the proposed equation is found to capture the association effects on the pressure and temperature dependence of the amine thermal expansivity.

TL;DR: In this article, an automated measuring device for (p, ρ, T ) data based on the vibrating tube principle is described and the reliability of whole configuration is checked through measurement and later comparison with recommended literature data for the 1-hexanol+ n -hexane binary system within the temperature and pressure ranges (278.15-333.15k) and (1−40k) respectively.

TL;DR: It is demonstrated that, even far from the critical point, the gradient theory is efficient to compute surface tensions and density profiles of this model fluid, provided the equation of state accurately model the phase behavior of the fluid involved (which is not the case for n=8 in this study).
