Elucidation of molecular interactions in the mixtures of 2-methoxyaniline with isomeric xylenes through transport and thermodynamic properties at T = 303.15, 308.15, and 313.15 K

ABSTRACT

Experimental values of the density (ρ), speed of sound (u), and viscosity (η) have been measured for binary mixtures of 2-methoxyaniline with toluene, and isomeric xylenes (o-xylene, m-xylene, and p-xylene) at temperatures of 303.15, 308.15, and 313.15 K over the entire mole fraction range. By using this data, the excess parameters (excess molar volumes, excess isentropic compressibility, and viscosity deviation) for the binary systems at the above-mentioned temperatures were calculated and fitted to Redlich–Kister equation to determine the fitting parameters and the root-mean-square deviations. The excess parameters have been analysed in terms of n–π interactions and dipole-induced dipole interaction between unlike molecules.
