Fickian and thermal diffusion coefficients of binary mixtures of isobutylbenzene and n-alkanes at different concentrations from the optical beam deflection technique.

We report the Fickian diffusion (D), thermal diffusion (D), and Soret (S) coefficients of 4 binary mixtures of isobutylbenzene (IBB) and n-alkanes (n-hexane, n-octane, n-decane, and n-dodecane) at 298.15 K and atmospheric pressure. The concentration is varied in the whole range.
