Ultrasonic velocities and densities of the binary liquid mixtures of o-chlorophenol with different aliphatic esters like methylacetate, ethylacetate and butylacetate are measured at temperatures 303.15, 308.15, 313.15 and 308.15K and atmospheric pressure. Theoretical velocities have been evaluated by using Nomoto (NOM), impedance (IMP), Van Dael and Vangeel (VDV), Junjie (JUN) and Rao’s specific velocity (RAO) models. A good agreement is found between experimental and theoretical values. U2 exp / U2 imx has also been evaluated for non-ideality in the mixtures. Chi-square test for the goodness of the fit is applied to understand the relative applicability of these theories to the present systems. The results are discussed in terms of intermolecular interactions between the component molecules in these binary liquid mixtures.
