Exploration of volumetric, acoustic, thermodynamic and IR studies of binary mixtures of green solvent ethyl lactate with C3 alkanols at T = (303.15, 308.15, 313.15 and 318.15) K and atmospheric pressure

Abstract Sound velocities (u) and densities ( ρ ) of the binary liquid mixtures of green solvent ethyl lactate (EL) with isopropyl alcohol (IPA), propylene glycol (PG), and glycerol (GLY) and also in pure solvents are measured over the entire composition range at temperatures (303.15, 308.15, 313.15 and 318.15) K and atmospheric pressure. The excess molar volume ( V m E ), excess isentropic compressibility ( k s E ), excess partial molar volumes ( V ¯ m , 1 E , V ¯ m , 2 E ) and excess partial molar volumes at infinite dilution V − 1 E , 0 and V − 2 E , 0 are computed from density and sound velocity measurements. These results are fitted to the Redlich–Kister polynomial equation to estimate the binary interaction parameters. The variation of these parameters with composition and temperature is discussed in terms of molecular interaction on mixing and their interacting abilities are compared.
