Volumetric properties of ternary mixtures of sulfolane with 2-alkoxyethanols and ethylene glycols at T = 303.15K

Abstract Densities of the ternary mixtures containing 2-methoxyethanol (2ME), 2-ethoxyethanol (2EE), 2-propoxyethanol (2PE), sulfolane (SULF) and ethylene glycols [ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), and tetraethylene glycol (TETRAEG)] have been measured, at T = 303.15 K and atmospheric pressure, over the whole composition range. From these experimental data, the excesses of molar volume ( V 123 E ) were calculated. These quantities were fitted to the Cibulka polynomial equation to derive the ternary adjustable parameters and standard errors. The results are discussed on the basis of intermolecular interactions between the components of the analysed mixtures.
