Spectroscopic thermodynamic properties of binary liquid mixtures of non-polar and polar solvents (Tetra chloromethane, 2-chloroaniline,2-methylaniline, and 2-methoxyaniline) at various temperatures

Abstract

The densities (ρ), viscosities (η) and speeds of sound(u) are reported for binary mixtures of tetrachloromethane with ortho-substituted aniline (2-chloroaniline, 2-methylaniline, and 2-methoxyaniline) over the entire composition range from 298.15 K to 318.15 K and at atmospheric pressure (0.1 MPa). The excess functions and deviation in viscosity are calculated from the densities, speeds of sound and viscosities at experimental temperatures. FT-IR properties have been carried out and analyzed to study the presence of specific interaction such as the formation of hydrogen bonding of the type (N-H·····Cl) between unlike molecules in the binary liquid mixtures. A good agreement is observed among the excess parameters and FT-IR properties.
