摘要This paper reports the solubility of alkali bromide MBr (M is Na or K) in ionic liquid (IL) EMISE (1-ethyl-3-methyliniidazolium ethyl sulfate), measured in the temperature range of 293.15-343.15 K. The relationship between solubility, in, and temperature, T, may be expressed in an empiric formula: ln(m/m0) = A(1) + A(2)T(0)/T, where T-0 is 1 K, m(0) is 1 mol kg(-1). The observed sequence of solubility is NaBr > KBr. The fact implies that the less the radius of alkali ion, the greater is its solubility because small ion is easy to get into the interstices of IL EMISE. In addition, the standard transfer thermodynamic functions of MBr from water to IL EMISE were calculated in terms of solubility data of MBr in water. Using Born model, the dielectric constant, D = 8.7, was estimated and was close to the value of typical IL measured by Wakai. (c) 2007 Elsevier B.V. All rights reserved.
