By an Arnold cell technique, the diffusion coefficients of propanol
and methanol in mixtures of air and argon system have been determined.
The carbon tetrachloride-air system was also studied to verify
the reproducibility of the experimental method.
The diffusion coefficients were compared with experimental
values when available and with values evaluated from empirical equations.
Comparison between the empirical and experimental data was
found to be reasonably good. The diffusion coefficients were measured
at 760 mm and 25° C except for the propanol-air-argon system which
was measured at 45° C
