VAPOR-LIQUID-EQUILIBRIUM IN BINARY AND TERNARY AQUEOUS-SOLUTIONS OF POLY(ETHYLENE GLYCOL) AND DEXTRAN

Abstract:
Activities of water for various binary and, in particular, ternary aqueous solutions of poly(ethylene glycol) (PEG) and dextran were measured over the entire homogeneous mixing range up to a polymer weight fraction of 0.3 at 293.15, 313.15, and 333.15 K. The water activities were determined by vapor-pressure osmometry and, additionally, for dilute dextran solutions using membrane osmometry. The experimental data were evaluated using the osmotic virial equation.
