摘要：

Fundamental thermodynamic data for the alpha-linolenic acid ethyl ester-carbon dioxide system and the gamma-linolenic acid ethyl ester-carbon dioxide system have been obtained under supercritical conditions. Critical loci, phase behavior, and partial molar volume measurements have been undertaken for a limited range of concentrations of both ethyl linolenate isomers. The Peng-Robinson equation of state, while providing acceptable qualitative predictions of system behavior, did not provide reliable quantitative correlations of the experimental data.
