Alonso Tristán, Cristina Alves Laurentino, João Victor Pazoki, Fatemeh Villa Vallejo, Susana Lozano Martín, Daniel Hevia de los Mozos, Luis Fernando Producción Científica Liquid-liquid equilibria phase diagrams have been determined for the systems: 2-methoxyphenol + n-decane, or + n-dodecane, or + n-tetradecane or + n-hexadecane and for 2-ethoxyphenol + n-octane, or + n-dodecane, or + n-tetradecane, or + n-hexadecane. The experimental method used is based on the observation, by means of a laser scattering technique, of the turbidity produced on cooling when a second phase appears. All the mixtures studied show an upper critical solution temperature, which increases with the n-alkane size. Dipolar interactions between like molecules become stronger in the sequence: 2-ethoxyphenol < 2-methoxyphenol < phenol. Data available in the literature suggest that this relative variation is also valid for n-alkane mixtures containing other substituted anilines, characterized by having a second polar group. The dependence of the upper critical solution temperature on the molecular structure of the polar aromatic compound involved is shortly discussed in terms of intramolecular and steric effects. 2025-06-27 2025-06-27 2025 info:eu-repo/semantics/article Journal of Molecular Liquids, 2025, vol. 434, p. 127992 0167-7322 https://uvadoc.uva.es/handle/10324/76133 10.1016/j.molliq.2025.127992 127992 434 Journal of Molecular Liquids eng https://www.sciencedirect.com/science/article/pii/S0167732225011699 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
