- •
FA solubility in CO2 + ethanol at 20–40 MPa, 313–333 K and 5–10 mol% ethanol was obtained.
- •
FA solubility in CO2 + ethanol + water at 30 MPa and 323 K was measured.
- •
FA solubility in water and ethanol at atmospheric pressure was evaluated.
- •
FA solubility in CO2/ethanol (90:10) attained values 120 times higher than FA solubility in CO2.
- •
Modelling thermodynamically by Peng-Robinson equation of state.
