Ultrasonic speeds and isentropic compressibilities of {difurylmethane + (C1–C6) n-alkanol} binary mixtures at T = 298.15 K

Densities (ρ), and ultrasonic speeds (u) of {difurylmethane + (methanol or ethanol or propan-1-ol or butan-1-ol or pentan-1-ol or hexan-1-ol)} binary mixtures have been measured over the entire composition range at T = 298.15 K and atmospheric pressure. Excess isentropic compressibility coefficient, κsE, excess ultrasonic speeds, uE and excess intermolecular free length, LfE, of each binary system were calculated and correlated by the Redlich–Kister equation. The results are discussed in terms of possible intermolecular interactions and structural effects.
