A previously described method, based on considerations of hard-sphere
theory, is used for the simultaneous correlation of the coefficients o
f viscosity, self-diffusion, and thermal conductivity for the n-alcoho
ls, from methanol to n-decanol, in excellent agreement with experiment
, over extended temperature and pressure ranges. Generalized correlati
ons are given for the roughness factors and the characteristic volume.
The overall average absolute deviations of the experimental viscosity
, self-diffusion, and thermal conductivity measurements from those cal
culated by the correlation are 2.4, 2.6, and 2.0%, respectively. Since
the proposed scheme is based on accurate density values, a Tait-type
equation was also employed to correlate successfully the density of th
e n-alcohols. The overall average absolute deviation of the experiment
al density measurements from those calculated by the correlation is +/
- 0.05%.
