Mutual diffusion in aqueous solution of ethylene glycol oligomers at 25 °C

Abstract

Mutual diffusion coefficients have been measured, at 25 °C, for binary systems of some ethylene glycol oligomers in aqueous solution over the whole mole fraction range. The results have been combined with activity and intradiffusion data to calculate the velocity cross-correlation coefficients (VCCs). An attempt has been made to explain the results in terms of molecular interactions.
