Liquid-liquid equilibria for ternary systems containing ethyl esters, ethanol and glycerol at 323.15 and 353.15Â K

► LLE is important for design and operation of biodiesel purification process. ► The solubilities in ethanol systems are higher than those in methanol systems. ► Glycerol selectivity decreases with increasing ethanol mass fraction. ► Global deviations below 6% with CPA EoS. ► Transferability of CPA binary parameters to predict LLE of biodiesel systems.
