Abstract

Experimental liquid–liquid equilibrium (LLE) data were determined for the ternary aqueous mixtures of propionic acid with the two cyclic and aryl ketones (isophorone or acetophenone) at 298.2 and 308.2 K and 101 kPa. A type-1 LLE behavior was observed for the studied ternary systems. The local composition models of NRTL and UNIQUAC were applied to correlate the measured tie-line data, and the model binary interaction parameters were determined. The reliability of the NRTL parameters was confirmed using topological analysis related to the Gibbs tangent principle. The extraction capacity of the tested solvents was evaluated by the obtained solute distribution coefficients and selectivities. As a result, the effect of the solvent and temperature on the biphasic area was observed to be small. Accordingly, the selected ketones contain fairly high selectivities and seem to be proper extraction solvents for aqueous propionic acid.

评价丙酸与两个环酮和芳基酮水溶液的液-液平衡：测量和热力学模型

在298.2 K、308.2 K、101 kPa条件下，测定了丙酸与两环酮和芳基酮（异戊酮或苯乙酮）三元水相的液液平衡（LLE）。在所研究的三元体系中观察到1型LLE行为。利用NRTL和UNIQUAC的局部组成模型对实测联络线数据进行关联，确定了模型二元相互作用参数。利用吉布斯正切原理进行拓扑分析，确定了NRTL参数的可靠性。通过所得的溶质分布系数和选择性来评价溶剂的萃取能力。结果表明，溶剂和温度对双相面积的影响很小。因此，所选酮具有相当高的选择性，似乎是水溶液丙酸的适当萃取溶剂。

期刊介绍： The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
