Physicochemical properties of ethylene glycol, diethylene glycol, and triethylene glycol in the aqueous biotin solutions at variation of temperatures

The Density and Ultrasonic Velocity of biotin with glycols (Ethylene, Diethylene, and Triethylene) have been measured at different range of temperatures (288.15 K to 318.15 K) and for different concentrations. Ultrasonic and volumetric data has been used to calculate various parameters such as adiabatic compressibility, acoustic impedance, available volume, molar volume, intermolecular free length, Rao’s constant, Van Der Waal Constant, Wada’s constant, relative intensity, and effective molecular weight. The calculated various parameters suggest solute-solvent interactions occurring in the liquid mixtures. Some other parameters suggest dipole-dipole interactions or formation of complex or charge transfer interactions.
