Volumetric properties of binary mixtures of tetrahydrofuran, dimethyl adipate, 1-butanol and 2-butanol from (288.15 to 323.15) K and modeling by Prigogine-Flory-Patterson (PFP) and Extended Real Association Solution (ERAS) models
Abstract
In this work, experimental densities data of the binary system tetrahydrofuran + 2-butanol have been determined at eight temperatures, T=(288.15-323.15) K and atmospheric pressure and used for excess molar volume calculations. Also, partial molar volumes, excess partial molar volumes and partial molar volumes at infinite dilutions were calculated for further non-ideal behaviour of binary mixture. Excess molar volume, V-E, of experimental determined system tetrahydrofuran + 2-butanol, and four previously published binary systems, tetrahydrofuran + 1-butanol, dimethyl adipate + 1-butanol, dimethyl adipate + 2-butanol and dimethyl adipate + tetrahydrofuran were correlated with two models, Prigogine-Flory-Patterson (PFP) and Extended Real Association Solution (ERAS). In order to apply the proposed models additional data of ultrasonic speed of sounds for pure components, dimethyl adipate, tetrahydrofuran, 1-butanol and 2-butanol, were measured in the temperature range T=(288.15-323.15) K an...d at atmospheric pressure. Volumetric coefficients, thermal expansion coefficient alpha and isothermal compressibility kappa were calculated from density, ultrasonic speed of sound and isobaric heat capacity data. Isobaric molar heat capacities C-p,C-m at all temperatures for all pure components were obtained by correlation of literature data. Both models, PFP and ERAS were used for analysis of molecular interactions present in the investigated solutions.
