Abstract

The binary gaseous diffusion coefficients D₁₂ for chlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,1,1-trichloroethane, tetrachloroethene, 1,4-dioxane and octamethylcyclotetrasiloxane (OMCTS) diffusing in air (i.e. 80% nitrogen + 20% oxygen) were measured at about 283, 298, 313, 328 and 343 K, and at atmospheric pressure, by the capillary tube method of Stefan. The experimental results are compared with diffusion coefficients calculated via the first-order Chapman-Enskog approximation. Effective pair-potential parameters for the large organic molecules were estimated by several semitheoretical correlations, i.e. the methods of Tee, Gotoh and Stewart, of Stiel and Thodos, and of Halkiadakis and Bowrey. Agreement is highly satisfactory, the only exception being OMCTS + air, where deviations up to ca. 30% are observed.
