用反相气相色谱法（IGC）研究了离子液体1-己基-3-甲基咪唑氯（[HMIM]Cl）在343.15 ~ 373.15 K温度范围内的热力学性质。通过热力学参数（质量分数活度系数、Flory-Huggins相互作用参数、混合偏摩尔焓、吸附偏摩尔焓、无限稀释活度系数和溶解度参数）来判断[HMIM]Cl与所选溶剂在研究温度下的相互作用。结果表明，二氯甲烷、氯仿、四氯化碳、乙醇和甲醇是[HMIM]Cl的有利溶剂，而n-C-6 ~ n-C-9、环己烷、苯、甲苯、间二甲苯、丙酮、乙酸乙酯、四氢呋喃、醚、甲基和乙酸酯是[HMIM]Cl的不利溶剂。(C) 2014 Elsevier B.V.版权所有
Some thermodynamic properties for the ionic liquid 1-hexyl-3-methylimidazolium chloride ([HMIM]Cl) were investigated by inverse gas chromatography (IGC) method at temperatures from 343.15 K to 373.15 K. The thermodynamic parameters, including weight fraction activity coefficient, Flory-Huggins interaction parameter, partial molar enthalpy of mixing, molar enthalpy of sorption, activity coefficient at infinite dilution and solubility parameter, were obtained to judge the interactions between [HMIM]Cl and the selected solvents at the studied temperatures. The results showed that dichloromethane, chloroform, carbon tetrachloride, ethanol, and carbinol were the favorite solvents for [HMIM]Cl, while n-C-6 to n-C-9, cyclohexane, benzene, toluene, m-xylene, acetone, ethyl acetate, tetrahydrofuran, ether, methyl, and acetate were bad solvents for [HMIM]Cl.
