abstract

  • The activity of water In sdutionr of poly (ethyhme glycols)(PEGS, molecular weights 200, 600, 1500, 6000) was measured over a wide range of weigM fractions at 293.1, 313.1, and 993.1 K. The data were obtained by an isopktk method. A comparison between the measured actlvlties and predicted values by the UNIFAC method gives a good agreement for PEG 200 solutions only.
