High-pressure phase equilibria of the pseudo-ternary system carbon dioxide + ethanol + fish oil

Abstract

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.
