ABSTRACT
This paper reports the solubility of alkali chloride MCl (M is Li, Na and K) in IL EMISE was measured in the temperature range of 293.15K to 343.15 K. The relationship between solubility, m and temperature T may be expressed in an empiric formula: ln(m/m0) = A1 + A2T0/T+A3T/T0, where m0 is 1 mol/kg, T0 is 1K. The observed sequence of solubility is LiCl greater than NaCl greater than KCl. The fact implies that the less the radius of alkali ion, the greater is its solubility because little ion is easy to get into the interstices of IL EMISE.
