Theoretical velocities of binary liquidmixtures of orthochlorophenol (OCP) with 2-methoxyethanol(MOE), 2-ethoxyethanol(EOE) and 2- butoxyethanol(BOE), at T = (303.15, 308.15, 313.15, 318.15)K and atmospheric pressure, have been evaluated by using Nomoto (NOM), impedance (IMP),VanDael andVangeel (VDV),Junjie (JUN) and RaoÂ’s specific velocity (RAO) modwls. Ultrasonic velocities and densities of these mixtures have also been measured experimentally as a function of composition of OCP and temperature.Agood 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 investigate the relative applicability of these theories to the present systems. The results are discussed in terms of intermolecular interactions between the componentmolecules in these binary liquid mixtures.
