Vvh. Babu et al., ULTRASONIC VELOCITY AND EXCESS PARAMETERS OF CERTAIN HYDROGEN-BONDED LIQUID BINARY-SYSTEMS, Indian Journal of Pure & Applied Physics, 34(10), 1996, pp. 764-768
Ultrasonic velocity, viscosity and density in binary liquid mixtures o
f N,N-dimethyl formamide, with O-chlorophenol, O-cresol and in dimethy
l sulphoxide with O-chlorophenol, O-cresol have been determined at 30
degrees C over the entire composition range. From the measured paramet
ers, isentropic compressibilities, intermolecular free length, excess
volumes, excess adiabatic compressibilities excess viscosities, and ex
cess free lengths have been calculated. Excess adiabatic compressibili
ties, excess free lengths and excess volumes of mixtures exhibit negat
ive deviations whereas excess viscosities exhibit positive deviations
from ideal behaviour over the entire mole fraction range.
