K温度范围内的热力学参数。使用了一系列不同化学结构的探针分子测定[ HMIM]BF4与溶剂之间的相互作用力。根据探针分子的保留时间计算得到探针分子与[ HMIM]BF4之间的 Flory-Huggins相互作用参数、摩尔吸附焓、无限稀释摩尔混合焓、摩尔蒸发焓、无限稀释活度系数以及[ HMIM]BF4的溶解度参数。结果表明，n-C6、n-C7、n-C8、n-C9、乙醚、四氢呋喃、苯、环己烷为[ HMIM]BF4的不良溶剂；甲苯、间二甲苯、甲醇、乙醇、二氯甲烷、四氯化碳、氯仿、丙酮、乙酸乙酯、乙酸甲酯为[ HMIM]BF4的良溶剂。运用外推法得到了[ HMIM]BF4在室温（298.15K）时的溶解度参数为23.70（J·cm-3）0.5。实验结果证明反气相色谱法是一种简便准确的获得离子液体热力学参数的方法。获得的热力学参数体现了这种离子液体与探针分子之间的相互作用力。本研究为离子液体的进一步应用提供了参考。","authors":[{"authorName":"李晓<span
