Abstract The composition of coexisting phases for liquid-liquid and solid-liquid-liquid equilibria were measured at 298.2 and 313.2 K and under atmospheric pressure for the following systems: {sodium bromide + formamide + ethyl acetate}, {sodium thiocyanate + ethanol + ( R )-limonene}, and {sodium thiocyanate + methanol + dibutyl ether}. These concentrations were determined mainly by chromatography and, for the first system, with the help of argentometric titration. The standard uncertainties in mole fractions varied between 0.001 and 0.008. The tie-line data were reproduced by the NRTL model with medium accuracy. Several empirical equations were used and tested to correlate binodal curves. The rational form of the equation, based on the liquid–liquid–solid tie-line, turned out to be the most adequate.

Journal of Solution Chemistry

溶液化学杂志为物理化学、化学物理、分子生物学、统计力学、生物化学和生物物理学等领域的液体溶液物理化学研究提供了一个论坛。重点是溶剂起主导作用而非偶然作用的论文。特色主题包括对液体溶液中电解质和非电解质的介电、光谱、热力学、传输或弛豫特性的实验研究。

The Journal of Solution Chemistry provides a forum for research in the physical chemistry of liquid solutions across various fields, including physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The journal emphasizes papers where the solvent plays a dominant role rather than a coincidental one. Featured topics include experimental studies of dielectric, spectral, thermodynamic, transport, or relaxation properties of electrolytes and non-electrolytes in liquid solutions.
