摘要：

The binary diffusion coefficients of palmitic acid (C16:0) ethyl ester were measured in supercritical carbon dioxide using a capillary peak broadening technique. Measurements were obtained in the temperature range of 308-318 K and at pressures between 96.7 and 210.5 bar. In addition, the applicability of several correlations to predict the diffusion coefficients of fatty acid ester-carbon dioxide systems determined by other workers was assessed. The models based on molecular connectivity were found to be the most quantitative in prediction of diffusion coefficients and were also found not to be system specific.
