ABSTRACT
The binary diffusions of ethyl benzoate, benzylacetone, and 2-methoxy-4-(2-propenyl)phenol (eugenol) at infinite dilution in supercritical carbon dioxide were measured between (15.0 and 35.0) MPa and in the temperature range of (313 to 333) K by the Taylor-Aris chromatographic method. The measured values were compared with the calculated ones using several predictive formulas. The effect of temperature, pressure, viscosity, and density is also discussed.
