Abstract
A high pressure, variable-volume visual cell was used to perform static mea surements of phase equilibria involving carbon dioxide and two different fa tty acid ethyl esters: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) ethyl esters. Six temperatures ranging from 303.15 to 353.15 K were selected. In a second step, our data were compared with predictions obtaine d by two group contribution based models previously published. Both models are able to predict with quite high accuracy our data whatever the temperat ure. (C) 2001 Elsevier Science B.V. All rights reserved.
