ABSTRACT

Speeds of sound u, isentropic compressibilities US, Rao!|s molar sound functions R, intermolecular free lengths Lf, specific acoustic impedances Z, excess molar volumes Em V , excess isentropic compressibilities E poundseS , excess intermolecular free lengths Ef L 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!V 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.
