Ultrasonic speeds and volumetric properties of binary mixtures of water with poly(ethylene glycol)s at 298.15 K

Ultrasonic studies of liquid mixtures of either water or dimethylsulfoxide with ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,2-propylene glycol and 1,4-butylene glycol at 298.15 K

“…The V E , u E and k E s values were fitted to the Redlich-Kister polynomial equation and the A k coefficients were derived. A survey of the available literature revealed that density data for binary mixtures of DMSO with EG, DEG and TrEG have been reported by Naidu et al [16], while acoustic data for binary mixtures of water with EG, DEG, TrEG and TetrEG have been published by Douhe´ret et al [17].…”

Raman spectroscopic study of the hydration of short-chain poly(oxyethylene)s C 1EnC 1 (n=1−4)

“…In this conformation the distances between the oxygen atoms of the O-CH 2 −CH 2 −O groups (2.9Å) coincide essentially with those between the oxygen atoms of neighboring water molecules in bulk water (2.85Å), allowing proper incorporation of POE chains into the structure of liquid water [6]. The idea of a partially hydrophobic-like hydration of POE in dilute aqueous solutions is supported by the observed slightly increased partial molar volumes of water [7][8][9], the reduced rotational mobility of hydration water [10][11][12] and the improved tetrahedral coordination [3,4] of hydration water in dilute aqueous solutions of short-chain POEs compared to the case of pure water. There are, however, differences between the hydration of POE in dilute solutions and hydrophobic hydration.…”
