We have measured the Soret coefficients of 41 out of 45 possible equimolar binary mixtures of 10 different organic solvents and found an additive rule for the heats of transport. These can, except for an undetermined offset, uniquely be assigned to the pure components. Based on their heats of transport, the fluids can be arranged according to their thermophobicity, similar to the standard electrode potential. A qualitative explanation of this unexpected additivity is based on the work of Morozov [Phys. Rev. E 79, 031204 (2009)].
我们已经测量了 45 种等摩尔二元混合物中的 41 种，这些混合物由 10 种不同的有机溶剂组成，发现了热输运的加和定则。这些除了一个未确定的偏移量外，可以唯一地分配给纯组分。基于它们的热输运，这些流体可以根据它们的疏温性进行排列，类似于标准电极电位。这种出乎意料的加和定则的定性解释基于 Morozov 的工作[Phys. Rev. E 79, 031204 (2009)]。
