摘要：
Binary diffusion coefficients of benzene, toluene, ethylbenzene, n-propylbenzene, isopropylbenzene, o-xylene, m-xylene, p-xylene, cumene, and mesitylene in CO2 as a supercritical solvent were determined using the Taylor-Aris dispersion technique. The supercritical fluid phase linear 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.
