Binary diffusion coefficients in supercritical fluids: Recent progress in measurements and correlations for binary diffusion coefficients

Dr. Aydin Akgerman greatly contributed to studies on diffusion in liquids and supercritical fluids, in particular, measurements by the Taylor dispersion method. Based on his work, this article describes recent progress in measurements for binary diffusion coefficients in supercritical fluids by using the chromatographic impulse response technique as well as the Taylor dispersion method, and in the predictive empirical correlations. The data reported in the literature and the proposed correlations are also briefly reviewed together with the research subjects to be investigated in future. (c) 2006 Published by Elsevier B.V.
