Resumo

Phase diagrams of systems composed of polyethylene(glycol) (PEG) 1500 + sodium citrate + water and PEG 4000 + sodium citrate + water were determined at temperatures of (10, 35, and 45) °C and (5, 10, 25, 35, and 45) °C, respectively. The influence of temperature and PEG molar mass on the equilibrium data of the system was analyzed. Binodal curves shifted toward the origin with the increase in PEG molar mass.
