00925njm 22002777a 4500 dc Lapeira, Estela author Bou-Ali, M. Mounir author 2016 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. 0938-0108 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=125049 https://hdl.handle.net/20.500.11984/5657 Thermodiffusion Binary mixtures Soret effect Thermophysical properties Thermogravitational column Thermodiffusion Coefficients of Water/Ethanol Mixtures for Low Water Mass Fractions
