Kirkwood-Buff 积分值是根据整个成分范围内 12 种水和有机溶剂的二元混合物的适当热力学数据获得的。根据这些数据评估混合物中每个分子的环境的局部组成，并以优先溶剂化参数表示。这些与混合物中发生的同分子和异分子相互作用有关。研究的系统是水与过氧化氢、1,2-乙二醇、2-丙醇、甲酸、乙酸和丙酸、甲酰胺、N-甲基甲酰胺、N,N-二甲基甲酰胺、N-甲基乙酰胺、六甲基磷三酰胺、环丁砜、碳酸丙烯酯和三乙胺的混合物。
Values of the Kirkwood–Buff integrals have been obtained from suitable thermodynamic data for 12 binary mixtures of water and organic solvents over the entire composition range where appropriate. The local composition of the environment of each molecule in the mixture is evaluated from these data and is expressed in terms of preferential solvation parameters. These are related to the homo- and hetero-molecular interactions that take place in the mixtures. The systems studied are mixtures of water with hydrogen peroxide, 1,2-ethanediol, 2-propanol, formic, acetic and propanoic acids, formamide, N-methylformamide, N,N-dimethylformamide, N-methylacetamide, hexamethyl phosphoric triamide, sulpholane, propylene carbonate and triethylamine.
