Binary diffusion coefficients at high dilution are measured for ethane and ethylene dissolved in cyclohexane at temperatures from 280.5 to 363.2 K and for benzene in cyclohexane and n-hexane up to their critical temperatures. With the effective hard-sphere diameters backed out from self-diffusion data from both solute and solvent molecules and fitted to Protopapas, Anderson, and Parlee's formula, the prediction with the Sung–Stell theory is found to agree to within ±7% of experimental data for wide ranges of solute-to-solvent mass and size ratios at temperatures up to the critical point.
