Abstract
The interaction of EG, DEG and TEG with biologically active D-Panthenol, as the function of temperature has been investigated by the combination of acoustic and volumetric methods. Speeds of sound and densities of EG, DEG and TEG in (0.05, 0.10 and 0.15) mol·kgâ1 in aqueous solutions of D-Panthenol have been measured at Tâ¯=â¯(293.15, 298.15, 303.15 and 308.15) K. From the density data, the apparent molar volume (VÏ0) and standard partial molar volume of transfer ÎVÏ0 for EG, DEG and TEG in aqueous D-Panthenol solutions have been determined. From the speed of sound data, the partial molar isentropic compression KÏ,s and the partial molar isentropic compression of transfer ÎKÏ,s0, have been determined. The pair and triplet interaction coefficient have also been estimated.
