文摘
Measurements of binary diffusion coefficients of aniline, styrene, and mesitylene have been carried out by meansof the Taylor-Aris chromatographic method. The diffusivities of mesitylene are consistent with those of Su

Chem. 1987, 59, 1164-1170) at low densities. Thenew data for styrene do not agree with those of Suaacute.gif">rez et al. Of the many predictive equations tested, the onlytwo that can predict the experimental data of the three substances reasonably well are the expressions of Sitaraman-Ibrahim-Kuloor (J. Chem. Eng. Data 1963, 8, 198-201) and Eaton-Akgerman (Ind. Eng. Chem. Res. 1997, 36,923-931), although both predict that aniline diffuses faster than styrene, which does not appear to be the case.
