气相色谱法测定醇在环丁砜+KCNS混合固定液中的无限稀释活度系数

The measurement,of infinite Activity Ceefficients of Some Alcohols in Sulfolane+KCNS Solutions by Gas Chromatography

在有限浓度条件下,含醇多元系的热力学性质由于液态醇的缔合结构而显得复杂。醇浓度无限稀时,为研究排除醇的自身缔合作用时溶质-溶剂相互作用,提供了特殊的条件。许多作者用气液色谱法(GLC)测定了这种条件下溶质在非电解质溶液中的无限稀释热力学参数。

Intinite activity coeficients (r1∞)of some C1~C4 alcohol solutes in KCNS+ sulfolane Solution at 60℃ were measured by gas chroawtography.The effect of alcohol's molecular structure on r1∞ and the effect of salt oa solute-solvents interaction,are discassed with the concept of pieratti's group interaction contribution and the relation
