چکیده
Densities ρ, Speeds of sound u, isentropic compressibilities κ s , intermolecular free lengths L f , specific acoustic impedances Z, relative association R a , intermolecular attraction α, excess molar volumes VE, excess isentropic compressibilities κ s E, excess intermolecular free lengths L f E 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.
