Volumetric properties of aqueous solutions of ethylene glycol oligomers at 25 °C
Abstract
Densities have been measured of aqueous solutions of ethylene glycol oligomers at 25 °C. Expressions for the limiting partial molar volumes were obtained: V2=V02+V22X2. Both V02 and V22 were found to be linear functions of the ethoxy group (—CH2—O—CH2—) number. The Kirkwood–Buff theory was used to interpret the V2 behaviour.
