摘要
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.
