Acoustic and Excess Thermodynamic Properties of Higher Alcohol with Alkylamine in Cycloalkane Medium at 303 K, 308 K

Ultrasonic velocities and percentage deviation in velocities have been calculated in the ternary mixture of Hexan-1-ol with N, N, Diethylethanamine in Cyclohexane medium at two different temperatures 303 K and 308 K. The adiabatic compressibility, free length, molecular interaction parameter, molar compressibility, acoustic impedance, molar volume, available volume, Leonard Jones potential, molar sound velocity, relative association and along with some of the excess parameters have been calculated. These calculated acoustic and excess thermodynamic parameters are used to discuss in terms of molecular interactions. The decreased values of ultrasonic velocity are shown for the entire mole fraction is identified. Even though the system of components having highly polar (Hexan-1-ol) and weakly polar (N, N, Diethylethanamine) substances the weak interactions among the molecules is resulted. The ultrasonic velocities have been computed theoretically using Nomoto's relation, Van Dael ideal mixing relation and Schaaff's Collision factor theory and compared with the experimental values. The calculated ultrasound velocity values of Nomoto's relation are best suited with experimental values. This kind of calculation is the evidence of theoretical approach of ultrasonic studies in liquid mixtures without doing experimental work. The values of different concentrations in liquid mixtures are discussed in terms of molecular interactions. The relative goodness of relations and theory are discussed.
