Investigation on thermophysical properties of binary systems of [C(4)mim [NTf2] with cyclic ethers: Application of PFP and ERAS theories
Room temperature ionic liquids (RTILs) have been researched as a novel substitute for volatile organic solvents since their inception two decades ago. The high viscosity and cost of pure !Bare major constrains for their industrial application which can be overcome by the addition of small amount of organic solvent. The introduction of organic solvents in pure ILs makes noticeable alteration in thermophysical properties of pure IL through variations in the molecular interactions. This manuscript deals with the excess molar volumes V-m(E), excess molar isentropic compressibili ties K-s,m(E) and logarithm of viscosi ties In eta(m) for binary systems of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C(4)mim][NTf2]) with two cyclic ethers: tetrahydrofuran (THF) and 1,4 dioxane (D10), at entire mole fraction range of IL and temperature between 298.15 K to 323.15 K. The V-m(E), K-s,m(E) and In eta(m) were calculated from the experimental values of densities, rho, speeds of sound, u, and viscosities, eta, respeclively. The Redlich-Kister polynomial equation was utilized to obtain fitting parameters for V-m(E), K-s,m(E) and In eta(m). The values of V-m(E), K-s,m(E) and In eta(m) were negative. The negative deviation from ideality was ascribed to efficient packing and presence of strong-ion dipole interactions in the binary systems. The negative deviation was more pronounced in binary system of [C(4)mim][NTf2] + THE than [C(4)mim][NTf2] + DIO. The values of In eta(m) decrease with rise in the temperature for both systems. The Prigogine-Flory-Patterson (PEP) theory and Extended Real Association Solution Model (ERAS) were employed to correlate experimental V-m(E). (C) 2020 Elsevier B.V. All rights reserved.
