The densities and speed of sound of the binary mixture1, 4-butanediol with γ-picoline have been measured over the entire composition range in the temperature range 303.15 to 318.15 K at ambient pressure. From the experimental data, the excess molar volume, excess isentropic compressibility and excess molarisentropic compressibility have been calculated. The excess partial molar volume, excess partial molar isentropic compressions and their limiting values at infinite dilution have also been calculated. Excess parameters are fitted to the Redlich- Kister polynomial equation. The variations of these parameters with composition and temperature are discussed in terms of intermolecular interactions.

Abstract


The densities and speed of sound of the binary mixture1, 4-butanediol with γ-picoline have been measured over the entire composition range in the temperature range 303.15 to 318.15 K at ambient pressure. From the experimental data, the excess molar volume, excess isentropic compressibility and excess molarisentropic compressibility have been calculated. The excess partial molar volume, excess partial molar isentropic compressions and their limiting values at infinite dilution have also been calculated. Excess parameters are fitted to the Redlich- Kister polynomial equation. The variations of these parameters with composition and temperature are discussed in terms of intermolecular interactions.
