The 1-octanol-water partition coefficient is an important property to measure the hydrophobicity of organic compounds, which has been demonstrated to be a parameter in studying the conformation of biomolecules in aqueous solutions. For biological systems, electrolytes play an important role in thermodynamic properties. The salt addition effect on the distribution of phenolic compounds between water and 1-octanol at 298.15 K has been studied. The phenolic compounds used were vanillic acid, protocatechuic acid, vanillin, tyrosol, cathecol, caffeic acid and syringic acid, and the considered salts were potassium chloride, sodium chloride and lithium chloride. The influence of both the concentration and size of the added salt on the partition coefficient (K _ow) have been considered. This study shows a salting in with the following decreasing order: LiCl > NaCl > KCl. The Gibbs energies of transfer of phenolic compounds (168–1) form chloride solutions to organic phase have been calculated using experimental 1-octanol-water partition coefficients.

298.15 K下盐的添加对1-辛醇-水系统中磨坊废水中某些酚类成分分配系数的影响。

1-辛醇-水分配系数是测量有机化合物疏水性的重要属性，已被证明是研究水溶液中生物分子构象的参数。对于生物系统，电解质在热力学性质中起重要作用。研究了在298.15 K下加盐对酚类化合物在水和1-辛醇之间的分布的影响。所用的酚类化合物是香草酸，原儿茶酸，香兰素，酪醇，乙醇，咖啡酸和丁香酸，所考虑的盐是氯化钾，氯化钠和氯化锂。添加盐的浓度和大小对分配系数的影响（K _ow）已被考虑。这项研究显示了按以下降序盐化：LiCl> NaCl> KCl。使用实验性的1-辛醇-水分配系数计算了从氯化物溶液到有机相的酚类化合物（168-1）的吉布斯转移能。
