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 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%.
