摘要
报道了LiBr在离子液体EMISE(硫酸乙酯-1-甲基-3-乙基咪唑)中的溶解度m/mol.kg-1.得到了溶解度和温度T之间关系的经验公式:lnm/m0=-4.09056+474.9163 T0/T+9.716×10-3T/T0.利用文献中LiBr在水中溶解度数据,计算了LiBr从水相至EMISE的标准迁移热力学函数.
The solubility of lithium bromide LiBr in ionic liquid (IL) EMISE ( 1-ethyl-3-methylimidazoli- um ethyl sulfate) was measured in the temperature range of 293.15 K to 343.15 K. The relationship between the solubility (m), and temperature (T), may be expressed in an empiric formula: In m/m°=-4.09056+474.9163 T°/T+9.716×10^-3 T/T°, where m is molality, T° is 1 K, m° is 1mol·kg^-1. The standard transfer thermodynamic functions of LiBr from water to IL EMISE were calculated in terms of solubility data of LiBr in water.
