Thermophysical properties of binary blends of cyclohexane with some esters
From the densities (ρ) and viscosities (η) measured for three binary blends consisting of methyl acetate (MA), ethyl acetate (EA) and methyl salicylate (MS) over the entire composition range with cyclohexane (CH) at 298.15–318.15 K under atmospheric pressure, the excess molar volumes (VEm ) and exc...

| description | From the densities (ρ) and viscosities (η) measured for three binary blends consisting of methyl acetate (MA), ethyl acetate (EA) and methyl salicylate (MS) over the entire composition range with cyclohexane (CH) at 298.15–318.15 K under atmospheric pressure, the excess molar volumes (VEm ) and excess viscosities (ηE) were derived. In addition, the excess isentropic compressibilities (KEs ) excess intermolecular free lengths (LEf) and excess molar refractions (R Em) were derived from measured ultrasonic speeds of sound (u) and refractive indices (nD) for the binary blends at 298.15 K. Various derived properties are discussed in terms of molecular interactions and structural effects. Partial molar volumes ( 0 Vm,1 and 0 Vm,2 ) and excess partial molar volumes ( 0,E Vm,1 and 0,E Vm,2 ) at infinite dilution are also discussed in terms of volume changes in the blends. Furthermore, the excess molar volumes (V Em ) and viscosities (η) of the blends were correlated with the Prigogine–Flory–Paterson (PFP) theory and the Peng–Robinson Equation of State (PR-EOS). |
