An inverse gas chromatographic method has been used to measure the solubility parameter of the dicationic ionic liquid, 1,10-bis(3-methylimidazolium-1-yl) decane hexafluorophosphate [C10(MIM)2][PF6]2, at the absolute temperatures from 343.15 K to 363.15 K. The test probe solvents were n-octane, n-dodecane, n-tetradecane, and n-hexadecane. The specific retention volumes of the solvents (Vg(0)), the molar enthalpy of sorption (DeltaH1(S)), the partial molar enthalpy of mixing at infinite dilution (DeltaH1(infinity)), the molar enthalpy of vaporization (DeltaHv), the activity coefficients at infinite dilution (gamma12(infinity)), Flory-Huggins interaction parameters (chi12(infinity)) between [C10(MIM)][PF6]2 and probe solvents were obtained. parameter (delta2) of [C10(MIM)2][PF6]2 was determined as 15.01 (J x cm(-3))(1/2), which was of great importance to the study of the solution behavior and application for ionic liquid.
采用反相气相色谱法测定了二价离子液体1,10-双(3-甲基咪唑鎓-1-基)癸烷六氟磷酸盐[C10(MIM)2][PF6]2在343.15 K至363.15 K绝对温度下的溶解度参数。测试探针溶剂为正辛烷、正十二烷、正十四烷和正十六烷。得到了溶剂的比保留体积(Vg(0))、吸附摩尔焓(ΔH1(S))、无限稀释下的混合偏摩尔焓(ΔH1(∞))、汽化摩尔焓(ΔHv)、无限稀释下的活度系数(γ12(∞))、[C10(MIM)][PF6]2与探针溶剂之间的弗洛里-哈金斯相互作用参数(χ12(∞))。[C10(MIM)2][PF6]2的溶解度参数(δ2)测定为15.01 (J·cm(-3))(1/2)，这对离子液体的溶液行为研究和应用具有重要意义。
