EXCESS PROPERTIES IN BINARY-LIQUID MIXTURES - TRI-N-BUTYL PHOSPHATE (TBP) AND 1-ALKANOLS

Excess isentropic compressibility (beta(s)E), excess ultrasonic veloci ty (C(E)), excess acoustic impedance (Z(E)), excess intermolecular fre e-length (L(f)E) and excess viscosity (eta(E)) have been computed from the measured ultrasonic velocity, viscosity and density in the binary liquid mixtures of tri-n-butyl phosphate (TBP) with 1-hexanol, 1-hept anol, 1-octanol and 1-decanol at 303.15 K. The results are discussed i n terms of molecular interactions between the component liquids in dif ferent systems. The nature of variation of these excess parameters pro vides information about the type of interaction taking place in these binary systems.
