CORRELATION AND PREDICTION OF DENSE FLUID TRANSPORT-COEFFICIENTS .6. N-ALCOHOLS

A previously described method, based on considerations of hard-sphere theory, is used for the simultaneous correlation of the coefficients of viscosity, self-diffusion, and thermal conductivity for the n-alcohols, from methanol to n-decanol, in excellent agreement with experiment, over extended temperature and pressure ranges. Generalized correlations 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 calculated 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 the n-alcohols. The overall average absolute deviation of the experimental density measurements from those calculated by the correlation is +/- 0.05%.
