2023-12-20T12:46:58Z urn:hdl:10259/8230 Preferential solvation and mixing behaviour of the essential oil 1,8-cineole with short–chain hydrocarbons Navarro Cuñado, A. Marta García Ruiz, Begoña Hoyuelos Álvaro, Fco. Javier Peñacoba Maestre, Indalecio A. Leal Villalba, José María Essential oils 1,8-Cineole Hydrocarbon Excess properties Preferential solvation This work deals with the structure and solvation ability of the binary mixtures of the essential oil 1,8-cineole with n-hexane, n-octane and n-decane. The relevant derived properties excess isobaric heat capacity, molar excess volume, mixing viscosity, excess isentropic compressibility and activation Gibbs free energy were calculated from the measurements of the respective thermophysical properties carried out at atmospheric pressure in a wide range of temperatures. The data obtained were correlated with the solvent composition over the whole range and interpreted in terms of structural features and molecular interactions. The observed effect of temperature and the underlying interactions stress the propensity of the pure hydrocarbons for packing and folding. The solvation ability of the mixed solvents was assessed with the preferential solvation model, using the solvatochromic probes 2-nitroanisole and 4-nitroaniline, and the Hansen solubility parameters as well, the mixtures displaying stronger solvation power than the pure constituents. 2023-12-20T12:46:58Z 2023-12-20T12:46:58Z 2016-12 info:eu-repo/semantics/article 0378-3812 http://hdl.handle.net/10259/8230 10.1016/j.fluid.2016.08.035 eng Fluid Phase Equilibria. 2016, V. 429, p. 127-136 https://doi.org/10.1016/j.fluid.2016.08.035 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
