Excess molar volumes, excess molar enthalpies and refractive index deviations for binary mixtures of propan-1-ol, butan-1-ol and pentan-1-ol with 2,2,4-trimethylpentane at 298.15 K

摘要: Abstract Density (ρ), refractive index (nD), and molar excess enthalpy (HE) of binary mixtures propan-1-ol with 2,2,4-trimethylpentane, butan-1-ol 2,2,4-trimethylpentane pentan-1-ol at 298.15 K ambient pressure have been experimentally measured in the whole composition range. Excess volumes (VE), deviation indices (ΔnD), deviations refraction (ΔR) HE data were correlated Redlich–Kister equation. Refractive indexes estimates carried out using several mixing rules. An estimation density mixture was performed equation suggested by Nakata Sakurai [35] Lorentz–Lorenz rule densities pure substances. Wilson Non Random Two Liquids (NRTL) models applied for correlation. The Prigogine–Flory–Patterson (PFP) Extended Real Association Solution (ERAS) theories used to correlate mixtures. behavior thermophysical properties analyzed terms length alkanol chain balance between positive negative ideality.
