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

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
