Binary mixtures of 2-methylcyclohexanone with various functional groups (m-cresol, p-cresol and o-chlorophenol)

Abstract

The densities , speeds of sound and viscosities including those of pure liquids, were measured for the binary mixtures of 2-methylcyclohexanone with various functional groups (m-cresol, p-cresol, and o-chlorophenol) over the entire composition range at different temperatures (303.15 - 318.15) K and atmospheric pressure 0.1MPa. Using this experimentally determined data, the values of excess molar volume, excess isentropic compressibility, partial molar volumes, partial molar isentropic compressibilities and deviation in viscosity of these components at infinite dilution were calculated. The results are discussed both in terms of acid-base interactions and the formation of π-π complexes between the, unlike molecules. Excess molar volume values have been analyzed with Prigogine- Flory-Patterson. Curves of excess molar volume ( V E ) with mole fraction for the binary mixtures of 2-methylcyclohexanone with p-cresol (■); m-cresol (▲) and (●)o-chlorophenol and at 303.15 K and (—) calculated with PFP theory using Parameters.
