Liquid-liquid equilibria experiments demonstrated that mixtures of 2-isopropoxyethanol and water saturated with NaCl are partially miscible. The lower critical solution temperature was estimated to be 29.2°C at a 2-isopropoxyethanol concentration of 0.399 (mIPE/(mIPE + mH(2)O)). Solid-liquid equilibria experiments showed that the solubility of NaCl in water is reduced significantly by the presence of 2-isopropoxyethanol. As in pure water, the NaCl solubility in 2-isopropoxyethanol-H2O mixtures increases weakly with temperature.
