Results of the DCMIX1 experiment on measurement of Soret coefficients in ternary mixtures of hydrocarbons under microgravity conditions on the ISS [Текст] / Galand Quentin, Van Vaerenbergh Stéfan, Köhler Werner, Khlybov Oleg, Lyubimova Tatyana, Mialdun Aliaksandr, Ryzhkov Ilya, Shevtsova Valentina, Triller Thomas // The Journal of Chemical Physics. — 2019. — Т. 151 (№ 13). — С. 134502Аннотация:
The Soret coefficients of a set of ternary systems of 1,2,3,4-tetrahydronaphthalene (THN), isobutylbenzene (IBB), and n-dodecane (nC12) at 298.15 K were measured under microgravity condition aboard the International Space Station in the frame of the DCMIX1 experiment. The present work includes a comprehensive study of possible data processing sequences for the interpretation of interferometric Soret experiments in ternary systems. Several data processing methodologies are discussed. A significant concentration dependence of the Soret coefficients is observed. In the present study, we have obtained large and positive values for THN and negative ones for IBB in all investigated systems. A linear relation between the Soret coefficients of two components is derived for each system and allows validating experimentally the coefficients measured in other experiments.
