Liquid−Liquid Equilibrium for Ternary Systems Containing a Sugar + a Synthetic Polymer + Water

Abstract

This paper presents phase equilibrium data for ternary liquid mixtures containing glucose or maltose + poly(propylene glycol)s or block copolymers of ethylene oxide and propylene oxide units + water. The nonrandom two-liquid (NRTL) and the universal quasi-chemical activity coefficient (UNIQUAC) models were employed to model phase equilibrium, allowing the calculation of phase compositions. Good agreement between the experimental data and the model results was achieved.
