Abstract
ABSTRACT Densities, ρ, and Speeds of Sound, u, were measured for pure liquids of ethyl acetate, (EtOAc), 1,2-butanediol, (1,2-BD), 1,3-butanediol, (1,3-BD), 1,4-butanediol, (1,4-BD) and their binary mixtures {x 1 EtOAc + x 21,2-BD}, { x 1 EtOAc + x 21,3-BD}, and { x 1 EtOAc + x 21,4-BD} over the composition (EtOAc) and at temperatures (298.15–323.15) K at pressure 0.1 MPa. To understand the molecular interactions of solute–solvent, measured excess properties such as the excess molar volume, , excess isentropic compressibility, , excess speeds of sound, , excess molar isentropic compressibility, , thermal expansion coefficient, , excess thermal expansion coefficient, were calculated and fitted using the Redlich–Kister equation. For better understanding, also calculated partial molar volumes/isentropic compressibilities, and their excess properties at infinite dilution were measured. These parameters have been used to understand the interactions in the mixtures qualitatively. The experimental findings were compared through the usage of theoretical model developed by Prigogine–Flory–Patterson (PFP).
