Abstract
A compilation of available experimental data for acetone-water mixtures with the reciprocal salt system Na+, K+ || Cl−, SO42−
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.
