Thermodiffusion Coefficients of Water/Ethanol Mixtures for Low Water Mass Fractions Lapeira, Estela Bou-Ali, M. Mounir Madariaga, Jose Antonio Santamaría, Carlos Thermodiffusion Binary mixtures Soret effect Thermophysical properties Thermogravitational column The difficulty of measuring the thermodiffusion coefficients by optical properties of water-ethanol binary mixtures of approximately 20 wt % of water has been highlighted by several authors in recent years. This is because the concentration derivative of the refractive index (∂ n/∂ c) p,T is near zero at this concentration. For this reason, we measured the thermodiffusion coefficients by means of density analysis using the thermogravitational column technique from 5 wt % to 50 wt % at 25∘C. In addition, we measured the thermophysical properties such as density, dynamic viscosity, thermal expansion and mass expansion. 2022-09-02T08:27:00Z 2022-09-02T08:27:00Z 2016 http://purl.org/coar/resource_type/c_6501 0938-0108 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=125049 https://hdl.handle.net/20.500.11984/5657 eng © 2016 Springer Science Business Media Dordrecht Springer
