Abstract

The binary gaseous diffusion coefficients at 1 atm pressure of sulfur hexafluoride with cyclohexane, methylcyclohexane, benzene, and toluene were measured at 10, 25, 40, 55 and 70°C by the capillary tube method of Stefan. Diffusion coefficients were calculated (a) by using Lennard-Jones (6, 12) pair potential parameters in conjunction with the Hudson-McCoubrey combining rule, and (b) with a semiempirical method somewhat similar to that suggested by Chen and Othmer . Diffusion coefficients calculated via method (b) were in much better agreement with experiment than those obtained via method (a).
