Abstract:
ABSTRACT Ultrasonic velocities, densities and viscosities of the binary liquid mixtures, butan-2-one with benzene and butan-2-one with carbon tetrachloride at 308 K by applying 2 MHz frequency over the entire mole fraction range. A detailed ultrasonic speed study on the binary liquid mixtures using thermodynamically derived acoustical parameters like free length, molecular interaction parameter, molar cohesive energy and internal pressure shows the extent of intermolecular interactions. Comparing the experimental values with theoretically evaluated ultrasonic velocities from Nomoto relation, Van Deal and Vangeel relation, Junjee relation and ideal mixing relation with different mole fraction range shows the interaction between the unlike molecules. Validity and application of these theories were correlated. Keywords: Butan-2-one, Acoustical parameters, intermolecular interactions, Nomoto
