Intermolecular Free Length

In the present study, the excess molar volume (VE) and the deviations in intermolecular free length (ΔLf), isentropic compressibility (Δβs), acoustic impedance (ΔZ), and ultrasonic velocity (ΔU) were calculated using the experimentally measured values of density (ρ) and ultrasonic velocity (U) of binary mixtures of an acidic organophosphoric extractant (DEHPA) with two substituted aromatic hydrocarbons, i.e., p-xylene and toluene at 303.15K and atmospheric pressure, 0.1MPa over the entire composition range of DEHPA. The results of both binary mixtures have been presented graphically and compared in terms of molecular interaction between unlike molecules of the mixtures, which outcome may be applied in the solvent extraction process.

Deviation In Isentropic Compressibility

Excess volumes and isentropic compressibilities for the binary mixtures of cyclohexanone, cylopentanone and 2-methylcyclohexanone with butylamine were determined at 303�15 and 313�15 K. Excess volumes of the three mixtures are negative over the whole range of compositions at both the temperatures. Deviations in isentropic compressibility are also negative in all the three mixtures. The results are ascribed to strong hydrogen bonding between unlike molecules. The results also suggest that cyclization decreases both √E and the deviation in isentropic compressibility.

Experimental Values

Densities, ultrasonic speeds and viscosities have been measured for benzyl alcohol, ethanol, propan-1-ol, octan-1-ol and for their binary mixtures with benzyl alcohol as common component at 303 K. From the experimental data, isentropic compressibility, relative association, acoustic impedance, molar sound velocity, excess volume, excess isentropic compressibility, deviations of viscosity and ultrasonic speed from linear dependence on composition, excess acoustic impedance and molecular association for all the three binary mixtures were obtained. These parameters have been interpreted in terms of intermolecular interactions. The experimental viscosity data of the three binary mixtures were used to test the validity of the empirical relations of Grunberg-Nissan, Tamura-Kurata, Hind-Mclaughlin, Katti-Chaudhary and Heric. The experimental values of ultrasonic speeds have been compared with those predicted on the basis of the Nomoto empirical relation, collision factor theory, free length theory and van Dael and Vangeel ideal mixing relation. The relative merits of these theories and relations are discussed.
