Volumetric and Acoustic Behavior of PEG-200 and PEG-600 in Aqueous D-Mannitol solutions at Different Temperatures

The interlinkage among the molecules of polyethylene glycols (PEG-200 and PEG-600) in aqueous D-Mannitol solutions are analyzed in the current investigation from the combination of acoustic and volumetric techniques. The densities and speeds of sound of the ternary mixtures of (water + d-mannitol + PEG-200/PEG-600) have been obtained at 293.15, 298.15, 303.15, 308.15 K as the function of D-mannitol concentration (0.01, 0.03 and 0.05) mol·kg−1...
