Binary diffusion coefficients for infinitely dilute solutions of aceto
ne, benzene, toluene, m-xylene, 1,3,5-trimethylbenzene, and naphthalen
e 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 a
ddition, the measurements for o- and p-xylenes, vitamin K3, linoleic a
cid methyl ester, indole, dl-limonene, vitamin A acetate, vitamin E, a
nd vitamin K1 in hexane and vitamin K3 and linoleic acid methyl ester
in dodecane were made at the limited conditions. The D12 results in th
e three solvents are expressed by the equation D12/T = alphaeta(beta)
with average absolute deviation of 5.2%, where eta is the solvent visc
osity and alpha and beta are constants related to the solute molar vol
ume at the normal boiling point. For the D12 measured in this study th
is correlation is as accurate as Nakanishi's correlation which is supe
rior to other correlations examined.
