Binary diffusion coefficients for infinitely dilute solutions of acetone, benzene, toluene, m-xylene, 1,3,5-trimethylbenzene, and naphthalene in hexane, in dodecane, and in cyclohexane were measured from 303.2 to 333.2 K and at 16.0 MPa using the Taylor dispersion technique. In addition, the measurements for o- and p-xylenes, vitamin K3, linoleic acid methyl ester, indole, dl-limonene, vitamin A acetate, vitamin E, and vitamin K1 in hexane and vitamin K3 and linoleic acid methyl ester in dodecane were made at the limited conditions. The D12 results in the three solvents are expressed by the equation D12/T = alphaeta(beta) with average absolute deviation of 5.2%, where eta is the solvent viscosity and alpha and beta are constants related to the solute molar volume at the normal boiling point. For the D12 measured in this study this correlation is as accurate as Nakanishi’s correlation which is superior to other correlations examined.
