Abstract
ABSTRACTThermodynamic and transport properties (excess molar volume, excess isentropic compressibility and deviation in viscosity) are calculated from the experimental density, speed of sound and viscosity. The results are analysed in terms of rupture of hydrogen-bonded chain as the dipolar interaction between 2-methoxyaniline and 1-alkanol (1-hexanol, 1-heptanol and 1-octanol) exceeds the intermolecular interaction through dipole-dipole and hydrogen bonding between these unlike molecules. The VE results are analysed in the light of Prigogine-Flory-Patterson theory. Analysis of each of the three contributions viz. interactional, free volume and P* to VE has shown that interactional contribution are positive for all systems, the free volume effect and P* contribution are negative for all the mixtures.
