Résumé :

Soret coefficients of aqueous solutions of methyl, ethyl, isopropyl, and n-butyl alcohols and of solutions of methyl and ethyl alcohols in benzene have been measured in the Soret coefficient measurement (SCM) experiment under microgravity conditions on board the orbital platform EURECA at a mean temperature of 37.5°C. These reference measurements will allow us to improve the understanding of the ground based results and to calibrate the ground based setup. This point is discussed with the values that we obtained by the flow cell technique and for systems that exhibited a hysteretic loop in the Schmidt-Milverton plots in the Bénard cell at a mean temperature of 37°C.
