Ultrasonic studies on binary mixtures of 1,4-dichlorobutane with some hydrocarbons at 308.15K, 313.15K and 318.15K

摘要

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.
