This study reports the densities, viscosities, and speeds of sound for binary mixtures of tetrachloromethane with ortho-substituted aniline, and analyzes the specific interactions such as hydrogen bonding between unlike molecules. Good agreement is observed between the excess parameters and FT-IR properties.
The densities (rho), viscosities (eta) 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 center dot center dot center dot center dot center dot Cl) between unlike molecules in the binary liquid mixtures. A good agreement is observed among the excess parameters and FT-IR properties. (C) 2021 Elsevier B.V. All rights reserved.
