Speeds of sound u, isentropic compressibilities κS, Rao's molar sound functions R, intermolecular free lengths Lf, specific acoustic impedances Z , excess molar volumes VmE, excess isentropic compressibilities κSE, excess intermolecular free lengths LfE and excess specific acoustic impedances ZE, of three binary mixtures of oxolane (tetrahydrofuran) with aniline, N-methylaniline and N-ethylaniline have been reported over the entire range of composition at 303.15, 313.15 and 323.15 K. The excess values have been fitted to Redlich–Kister polynomial equation. The results have been analyzed in terms of molecular interactions between oxolane and anilines. The speeds of sound in present binary mixtures have been estimated from various empirical and theoretical models.
