本文测定了5、15、25和35℃时KCl在甲醇-苯、甲醇-甲苯、甲醇-环己烷和甲醇-四氯化碳中的溶解度S,并得到经验公式:logS=a+bT,其中T为绝对温度。同时计算了KCl由甲醇到甲醇混合溶剂的标准迁移自由能ΔG,并得到它和组成x_(Ne)的经验关系式;ΔG=CX_(Ne)。同时指出在本实验范围内,温度的变化不影响单纯溶剂化模型和第二介质常数公式的适用性。
In this paper, the solubility of KCl in methanol-benzene, methanol-toluene, methanol-cyclohexane and methanol-carbon tetrachloride at 5, 15, 25 and 35 ℃ was measured and the empirical formula was logS = a + bT, Where T is the absolute temperature. At the same time, the standard migration free energy ΔG of KCl from methanol to methanol mixed solvent was calculated and the empirical relationship between it and composition x_ (Ne) was obtained. ΔG = CX_ (Ne). Meanwhile, it is pointed out that the change of temperature does not affect the applicability of the simple solvation model and the second dielectric constant formula within the scope of this experiment.
