Binary mixtures of 2-methoxyaniline with various functional groups (Thermodynamic and transport properties)

Abstract

Abstract In the binary mixtures of 2‑methoxyaniline with various functional groups (2-methylcyclohexanone, methyl benzoate, anisole and trichloroethene) the densities, speeds of sound and viscosities including those of pure liquids, were measured over the entire composition range at different temperatures (303.15, 30.18 and 313.15) K and atmospheric pressure 0.1 MPa. Using this experimentally determined data, the excess values of molar volume, 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 breaking hydrogen bonds in the amine and the formation of π-π complexes between the unlike molecules.
