摘要：

Binary diffusion coefficients, D12, in supercritical carbon dioxide were determined in a supercritical fluid chromatographic apparatus by the peak-broadening method. Organic compounds belonging to three different classes, namely ketones, fatty acids and liquid crystals and additionally squalene were investigated as a function of pressure between 9.5 and 18 MPa at about 314 K. The resulting D12 values are of the order of 10-8 m2 s-2 and 1n D12 decreases approximately linearly with increasng density of the carbon dioxide. © 1990.
