Abstract A compilation of available experimental data for acetone-water mixtures with the reciprocal salt system Na+, K+ || Cl−, SO4 2− is presented. Significant inconsistencies among experimental data are pointed out. New freezing point measurements are reported for the binary acetone-water system at 12 different compositions. UNIQUAC parameters are determined on the basis of the available data from literature. Modeling results are presented. Vapor-liquid, liquid-liquid, and solid-liquid equilibria together with thermal properties are reproduced well by the model using only 14 parameters. The major drawback of the model is that the calculated liquid-liquid equilibrium regions of systems with KCl and NaCl are larger than the experimentally determined regions. The model is valid in the temperature range from −16 to 100 °C.

模拟丙酮-水-盐系统的气-液-液-固平衡

摘要 丙酮-水混合物与倒盐体系 Na+, K+ || 的可用实验数据汇编 显示了 Cl-、SO4 2-。指出了实验数据之间的显着不一致。报告了 12 种不同成分的二元丙酮-水系统的新冰点测量值。UNIQUAC 参数是根据文献中的可用数据确定的。呈现建模结果。该模型仅使用 14 个参数就可以很好地再现汽液、液液和固液平衡以及热性能。该模型的主要缺点是计算出的 KCl 和 NaCl 系统的液-液平衡区域大于实验确定的区域。该模型在−16 到 100 °C 的温度范围内有效。
