• Density and sound speed measurement of (alcohol + TBP) mixtures between T = (298 and 323) K.
• Excess thermodynamic parameters calculated.
• The deviation from ideality interpreted in terms of intermolecular interactions.
Density (ρ) and speed of sound (u) of the binary mixtures of tributyl phosphate (TBP) and alcohols (1-octanol, 1-decanol and isodecanol) were measured at temperatures from T (298.15 to 323.15) K over the entire composition range and at atmosphere pressure. Using these experimentally determined quantities, the excess molar volume (VE), deviation in isentropic compressibility (Δκs), internal pressure (pi), and adjusted correlation coefficients have been calculated. The excess molar volume has been fitted to a Redlich–Kister type polynomial equation. The positive or negative deviations shown by the excess quantities and the trend shown by the adjusted correlation coefficients have been interpreted in terms of intermolecular interactions and structure of components.
