Thermodynamic and spectroscopic properties of binary liquid mixtures of 2-methylcyclohexanone and o- substituted anilines at various temperatures

Abstract

ABSTRACT The densities (ρ), viscosities (η), and speeds of sound (u) are reported for binary mixtures of 2-methylcyclohexanone with ortho-substituted anilines (2-chloroaniline, 2-methylaniline and 2-methoxyaniline) over the entire composition range from 303.15 K to 313.15 K and at atmospheric pressure 0.1 MPa. The excess functions and deviation in viscosity were calculated from the densities, speeds of sound, and viscosities at experimental temperatures. FT-IR properties have been carried out and analysed to study the presence of specific interaction such as the formation of hydrogen bonding of the type (O-H·····N or N-H·····O) between unlike molecules in the binary liquid mixtures, a good agreement is observed among the excess parameters and FT-IR properties.
