Vapor-liquid phase equilibrium of carbon dioxide with mixed solvents of DMSO + ethanol and chloroform + methanol including near critical regions

- Isothermal VLE phase boundaries were measured via synthetic method.
- The investigated systems are CO2 + DMSO + ethanol and CO2 + chloroform + methanol.
- The critical points of each pseudo-binary system were estimated from experimental results.
- The Peng-Robinson equation with van der Waals one-fluid mixing rules were used in this study.
