Ultrasound velocities (u) for binary liquid mixtures of methoxybenzene with several chlorohydrocarbons viz. dichloromethane, 1,2-dichloroethane, trichloroethene and tetrachloroethene at 293.15K and 303.15 K have been measured over whole concentration range. Adiabatic compressibilities (Ks) for the studied binary mixtures have been calculated from the experimental ultrasound velocity data. Ultrasound velocities increase and adiabatic compressibilities decrease with mole fraction of methoxybenzene at experimental temperature for all the systems studied. Results have been discussed in terms of molecular interactions between the components of the binary mixtures.Keywords

Ultrasound velocity and density of the binary mixtures of 1, 4-dichlorobutane with several hydrocarbons such as cyclohexane, benzene, methylbenzene, 1, 2-dimethylbenzene, 1, 4-dimethylbenzene and 1,3,5- trimethylbenzene have been measured over entire mole fractions range at three temperatures 308.15K, 313.15K, and 318.15K. Adiabatic compressibility has been evaluated from the experimental data. Ultrasound velocities increase with mole fractions of 1, 4-dichlorobutane at all the three experimental temperatures for 1, 4- dichlorobutane + cyclohexane system. The ultrasonic velocity decreases with molefractions of 1, 4-dichlorobutane for binary mixtures with all the aromatic hydrocarbons used at the three experimental temperatures. The adiabatic compressibilities decrease with mole fractions of 1, 4-dichlorobutane for all the binary mixtures studied at the three experimental temperatures. The deviations in adiabatic compressibilities from the ideal values have also been evaluated. At higher temperature, the values of ultrasonic velocity decreases while adiabatic compressibility increases for all the binary mixtures. The results are interpreted in terms of molecular interactions operating between the components of the binary mixtures.Keywords

Ultrasound velocities of binary liquid mixtures of some hydrocarbons, n-hexane, n-heptane and cyclohexane with isobutanol at 308.15 K and cyclohexane and carbon tetrachloride with n-heptanol at 306.15 K are evaluated using equations proposed by Nomoto,Van Dael and Vangeel, Jacobson relation based on intermolecular free length and Schaafs' equation based on collision factor theory. Sound velocities evaluated by above equations are compared with the experimental values. It is found that the ultrasound velocity evaluated on the basis of Schaafs' collision factor theory gives good agreement with the experimental values for the system studied. Non-ideality in the liquid mixtures has been discussed in terms of U2exp/U2imix where Uexp and Uimix are the experimental and ideal mixture velocities respectively.Full Text

Several acoustical parameters viz. free length (Lf ), Wada's constant (W), acoustical impedance (Z), available volume (Va) and relaxation time (τ) have been evaluated from the experimental values of ultrasound velocities (u) and densities (ρ) of the binary mixtures of 1,4-dichlorobutane with several hydrocarbons viz. cyclohexane, benzene, methylbenzene, 1,2-dimethylbenzene, 1,4-dimethylbenzene and 1,3,5-trimethylbenzene over entire mole fractions range at three temperatures 308.15K, 313.15K, and 318.15K. Lf values decrease for all the systems as molefraction of 1,4-dichlorobutane increase in the binary mixtures at the three experimental temperatures. Wada constant increase for binary mixtures of 1,4-dichlorobutane with cyclohexane, benzene and methylbenzene as mole fractions of 1,4-dichlorobutane increase and for other three binary mixtures it decrease. Z and τ values increases with molefractions of 1,4-dichlorobutane for all binary mixture except τ values for the binary mixtures with cyclohexane which decrease. Va values for binary mixtures of 1,4-dichlorobutane with benzene, methylbenzene and 1,2-dimethylbenzene increase and for other three experimental binary systems decrease as molefractions of 1,4-dichlorobenzene increase.Keywords
