Excess molar enthalpy measurement and modelling of (oxygenated compounds + hydrocarbon) mixtures: Binary and ternary mixtures containing 2-(2-methoxyethoxy)ethanol, 1-hexene and cyclohexane at (298.15 and 313.15) K

Abstract

NEW measurements and modelling data of excess molar enthalpy HE at atmospheric pressure and temperatures of (298.15 and 313.15) K using a quasi-isothermal flow calorimeter are presented in this work for the ternary system diethylene glycol monomethyl ether glycol (2-(2-methoxyethoxy)ethanol) + 1-hexene + cyclohexane and the corresponding binary systems over the whole composition range. All the binary and ternary systems present an endothermic behaviour at the chosen temperatures. The experimental data of the binary and ternary systems were correlated using the modified Redlich-Kister equation, NRTL and UNIQUAC models.
