IR spectroscopic-acoustical and surface tension studies of binary liquid mixtures at different temperatures T = (303.15, 308.15, 313.15 and 318.15) K

Abstract

Binary liquid mixture containing aniline and Mesitylene is used to obtain ultrasonic velocities and densities over the entire mole fraction range of aniline at temperatures T = (303.15, 308.15, 313.15 and 318.15) K. Temperature dependent acoustical parameters have been calculated from the experimentally measured values. Molecular association between the components of liquid mixture has been discussed on the basis of the temperature dependent acoustical parameters. From the recorded FTIR spectra, the non-ideal behavior of the liquid mixture studied was explained simultaneously on the basis of the C–H, N–H, C–N bond stretching. The variations in molecular interactions have been well supported by the computed values of surface tension.
