Mass effect on the soret coefficient in n-alkane mixtures Alonso de Mezquia, David Bou-Ali, M. Mounir Madariaga, Jose Antonio Santamaría, Carlos We have determined the Soret coefficient of different equimolar and non equimolar n-alkane mixtures from measurements of the molecular diffusion and thermal diffusion coefficients. It is shown that equimolar mixtures behave as isotopic-like mixtures in which only the mass effect contributes to the Soret effect. In non equimolar mixtures, a small linear dependence with the molar fraction is observed. Finally, we have obtained a new correlation, which allows the determination of the Soret coefficient of n-alkane mixtures using the data of viscosity, the thermal expansion coefficient of the pure components, and the density of the equimolar mixture. 2022-10-25T16:57:50Z 2022-10-25T16:57:50Z 2014 http://purl.org/coar/resource_type/c_6501 1089-7690 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=105613 https://hdl.handle.net/20.500.11984/5760 eng © 2014 AIP Publishing AIP Publishing
