Abstract
Binary diffusion coefficients of benzene, toluene, ethylbenzene, n-pro pylbenzene, isopropylbenzene, o-xylene, m-xylene, p-xylene, cumene, an d mesitylene in CO2 as a supercritical solvent were determined using t he Taylor-Aris dispersion technique. The supercritical fluid phase lin ear velocity dependence was confirmed in all systems, and the tendency of the dependence of the diffusivity on the molecular size and shape is quantitatively discussed. The influence of pressure and temperature for benzene was extensively studied.
