THERMODYNAMIC AND ACOUSTIC STUDIES ON VARIOUS BINARY LIQUID MIXTURES

Abstract

Acoustical and excess thermo physical properties of 2methylcyclohexanone with O-chloroaniline, O-toluidine explored at varying temperatures (303.15 318.15 K) and close gas pressure by evaluating speed of sound (u), density (ρ) and viscosity (η) over the total vary of composition. The trend in the acoustical and excess thermo acoustic parameters exhibit the existence of hydrogen-bonded and charge transfer complexes between the binary system. The variation of the excess parameters both in sign and magnitude in the full range of composition investigated. These results were fitted to Redlich-Kister polynomial equations to estimate the binary coefficients and standard errors. The partial and excess partial molar volumes for each component at infinite dilution have been appraised and reported.
