Densities ρ, Speeds of sound u, isentropic compressibilities κs, intermolecular free lengths Lf, specific acoustic impedances Z, relative association Ra, intermolecular attraction α, excess molar volumes VE, excess isentropic compressibilities κsE, excess intermolecular free lengths LfE and excess specific acoustic impedances ZE of acetophenone with ethyl cyanoacetate have been reported over the entire range of composition at 303.15, 313.15 and 323.15K. The excess values have been fitted to Redlich–Kister polynomial equation. The results have been analyzed in terms of molecular interactions between acetophenone and ethyl cyanoacetate. The speeds of sound in present binary mixtures have been estimated from various empirical and theoretical models.
