The additivity of surface and volumetric properties of α,ω-dihalogenoalkanes

Highlights: • The surface tension of α,ω-dibromo- and dichloroalkanes have been measured. • The surface entropy and surface enthalpy have been determined. • A predictive SAFT-VR-Mie-based model has been implemented. • This model truthfully estimates the surface tension data under consideration. -- Abstract: Surface tensions along the homologues series of α,ω-dibromo- and dichloroalkanes in the temperature range 293.15–313.15 K have been measured by the pendant drop method. The new atmospheric pressure density data for some of these compounds have been reported as well. Based on the current experimental surface tension data, the surface entropy and surface enthalpy have been determined. It has also been demonstrated that SAFT-VR-Mie attached by a predictive corresponding states correlation based on the description of fluid phase properties by means of Mie intermolecular potential accurately estimates some of the reported surface tension data and correctly describes their trends.
