文摘

(Liquid + liquid) equilibrium of (PEGDME + di-sodium hydrogen citrate + H2O) was studied.

The effect of temperature and polymer molar mass on the LLE were investigated.

Binodal data were fitted with two temperature dependent semi-empirical equations.

EEV model was used for study the effect of molar mass of polymer on the binodal.

Several equations including NRTL model were used to fit tie-lines.
