Abstract
The simple principle of corresponding states for the self-diffusion coefficient has been extended to binary diffusion coefficients at infinite dilution. A simple correlation based on this approach has then been developed and tested against available experimental data. For the 12 systems tested the average percentage error is less than 6% while the maximum and minimum errors are 30%, and 1%, respectively. An approximation is also suggested which permits this approach to be used for compositions other than infinite dilution.
