我们已经测量了41的45个可能的等摩尔二元混合物的10种不同的有机溶剂的Soret系数，并发现了一个添加剂规则的运输热。除了未确定的偏移量之外，这些可以唯一地分配给纯分量。基于它们的传输热，流体可以根据它们的疏水性来排列，类似于标准电极电势。这种意外加和性的定性解释基于Morozov的工作[Phys.Rev.E79，031204（2009）]。
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)].
