Abstract :

The interactions of triethylene glycol with glycerol have been examined with the help of volumetric and acoustic studies. The density and speed of sound for the mixtures of triethylene glycol and glycerol have been measured with the help of Anton Paar DSA 5000 M. The measured densities and speeds of sound are utilized to evaluate various quantum thermodynamic parameters such as acoustic impedance, intermolecular free length, adiabatic compressibility, molar volume, available volume, Wadaâ??s constant, Raoâ??s constant and Van der Waalâ??s constant. The variations in these parameters have been inspected and corresponding change in them has been discussed in terms of molecular interactions prevailing in the mixtures. The measured values of speed of sound have been compared with theoretically estimated values with the help of empirical models like Van Dael, Nomoto, Impedance dependence relation and Vangeels ideal mixing relation. The deviations of experimental ultrasonic speeds from theoretically estimated ultrasonic speeds have also been calculated. The studied parameters revealed the presence of strong intermolecular interactions in the mixtures of triethylene glycol and glycerol.
