Abstract

The binary gaseous diffusion coefficients of methane and carbon tetrafluoride with n-hexane, n-heptane, n-octane, and 2,2,4 trimethylpentane were measured at one atmosphere pressure and loo, 25°, 40°, 55°, and 7O°C by the capillary tube method of Stefan. The predicted diffusion coefficients calculated using Lennard-Jones potential parameters in the Chapman-Enskog approximate kinetic theory were about 2-6% low for the systems with methane and about 10-13% low for the systems with carbon tetrafluoride.
