文摘
- •
Isothermal phase equilibrium boundaries were measured via synthetic method.
- •
The investigated systems are ternary mixtures of CO2 + ethanol, DMSO, or DMF + water.
- •
The critical points of each pseudo-binary system were estimated from experimental results.
- •
The Peng-Robinson equation with Wong-Sandler mixing rule was used in this study.
