液体混合物中的分压和渗透压

Partial Pressures in Liquid Mixtures and Osmotic Pressures

Junzo Chihara, Mitsuru Yamagiwa

摘要:

本文证明了分压可以唯一地定义为液体混合物中某一组分所施加的壁面压力,是一个重要的可观测物理量。由于这个定义,分压定律适用于具有强相互作用的液体混合物。此外,本文还表明,混合物中的气-液相平衡是由两相间各组分的分压平衡建立的。因此,对于稀溶液,亨利定律,拉乌尔定律和范特霍夫定律可以根据分压的概念推导出来。

英文摘要:

We have shown in this investigation that the partial pressure can be defined uniquely as each wall pressure exerted by a component in liquid mixtures, and is an important observable physical quantity. As a consequence of this definition, the law of partial pressures is applicable to liquid mixtures with strong interactions. Furthermore, it has been shown here that the gas-liquid phase equilibrium in mixtures is established by the balance of each partial-pressure for every component between the two phases. Hence, for a dilute solution Henry's law, Raoult's law and van't Hoff's law can be derived on the basis of the concept of partial pressure.
