This work provides experimental phase equilibrium data of the pseudo-ternary system CO2 +
ethanol + fish oil, a system of interest in pharmaceutical and food-industry applications such
as the enzymatic production of fatty acid ethyl esters at mild, non-oxidative conditions.
Measurements were carried out in a high-pressure variable-volume view cell in the
temperature range 323.15-343.15 K and at pressures from 10 to 30 MPa. The Peng-Robinson
equation of state was used to satisfactorily correlate experimental data.
