Modeling vapor-liquid-liquid-solid equilibrium for acetone-water-salt system

“…The most serious shortcoming of the current modeling seems to be limited ability to defer the formation of LLE to temperatures above 32 °C [14]. Snell [14] determined the binodal curve of acetone-water solutions saturated with KCl. In Fig.…”

“…This system is interesting because NaCl, KCl, and Na2SO4 cause liquidliquid splits while K2SO4 does not. While NaCl cause liquid-liquid split down to at least -6°C [13], KCl only cause liquid-liquid split at temperatures above 32 °C [14]. According to Snell [14], the liquid-liquid split in acetone-water solutions with KCl continues up to at least 230 °C.…”

According to Snell [14], the liquid-liquid split in acetone-water solutions with KCl continues up to at least 230 °C. Experimental data for liquid-liquid split in acetone-water solutions with Na2SO4 have been reported in the 35-50 °C range.…”
