The activity of water In tetraethylene glycol solutions has been measured at 298.1 K. Vapor-llqutd equilibrium data In aqueous solutions of trl-and tetraethylene glycols are used to estimate the Interaction parameters for the UNIFAC group contribution model. The activity of water In poly (ethylene glycol) 300 and poly (propylene glycol) 400 Is calculated by the UNIFAC method. Good agreement with experimental data Is obtained for the former and moderate agreement for the latter.
