KCl在甲醇-非电解质的混合溶剂中溶解度和溶剂化
摘要:
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_(tr)~°-, 并得到它和组成x_(Ne)的经验关系式; ΔG_(tr)~°-=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。

THE SOLUBILITY AND SOLVATION OF KCI IN MIXED SOLVENTS
Abstract:
This paper reports our measurements of the solubility of KCI in the mixtures of methanol-benzene, -toluene, -cyclohexane, -carbontetraehloride at 278.16, 288.15, 298.15, 308.15 K. These data can be expressed by
log(S_o/S_m)=kx_Ne (1)
and
log(S_o/S_m)=k_φφ_(Ne) (2)
where S_o and S_m are the solubilities of salts in pure methanol and mixed solvent, respectively, x_(Ne) and φ_(Ne) are the mole fraction and volume fraction of nonelec- trolytes in the mixed solvent,respectively, k_φ is called the second medium cons- tant. ...
