abstract = {n this study, the thermodiffusion, molecular diffusion, and
Soret coefficients of 12 binary mixtures composed of
toluene, n-hexane and n-dodecane in the whole range of
concentrations at atmospheric pressure and temperatures of
298.15 K and 308.15 K have been determined. The experimental
measurements have been carried out using the
Thermogravitational Column, the Sliding Symmetric Tubes and
the Thermal Diffusion Forced Rayleigh Scattering techniques.
The results obtained using the different techniques show a
maximum deviation of $9\%$ for the thermodiffusion
coefficient, $8\%$ for the molecular diffusion coefficient
and $2\%$ for the Soret coefficient. For the first time we
report a decrease of the thermodiffusion coefficient with
increasing ratio of the thermal expansion coefficient and
viscosity for a binary mixture of an organic ring compound
with a short n-alkane. This observation is discussed in
terms of interactions between the different components.
Additionally, the thermogravitational technique has been
used to measure the thermodiffusion coefficients of four
ternary mixtures consisting of toluene, n-hexane and
n-dodecane at 298.15 K. In order to complete the study, the
values obtained for the molecular diffusion coefficient in
binary mixtures, and the thermodiffusion coefficient of
binary and ternary mixtures have been compared with recently
derived correlations.},
