Abstract
Densities (ρ), dynamic viscosities (η), refractive indices (n D) and speeds of sound (u) of binary mixtures of tetrahydrofuran with 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol and 1-decanol over the entire range of mole fraction, at temperatures 298.15, 303.15, 308.15 and 313.15 K and atmospheric pressure have been measured. Excess functions such as excess molar volume (V E), deviations in molar refractivity (ΔR m), deviations in speed of sound (u D), excess isentropic compressibilities () and viscosity deviations (Δη) have been calculated and fitted to the Redlich–Kister-type polynomial equation. The viscosity data were correlated with semi-empirical equations. The speeds of sound have been analysed in terms of collision factor theory and free length theory. The behaviour of V E, ΔR m and u D over the entire range of mole fraction, exhibited positive deviations, while and Δη showed negative variations.
