摘要
本文利用气液色谱法测定了333.15K时,C_(1-4)醇在碳酸丙烯酯-盐(NaI、NaSCN、NaClO_4)固定液中的无限稀释活度系数γ_(1)~.观察到:1.各溶质的Inγ_1~和固定液中盐的摩尔分数间具有较好的线性关系,且发生盐溶效应。2.在各个盐浓度的溶液中,醇同系物的Inγ_1~∞和醇分子碳数间存在着线性关系。并对实验现象从理论上进行了分析和讨论。
The gas liquid chromatographic method was used to detect the infinite activity coefficients of C_(1-4) alcohols in solutions of propylene carbonate (PC) and salt (NaI, NaSCN, NaClO_4). The coefficient of salting-in effect was calculated. Experimental result shown: 1, there was a linear relationship between In of alcohols with salt concentration in stationary solutions, and the salting-in effect exists. 2, in various salt conoentration solution, another linear relationship between In of normal alcohols with its carbon number also exist. The experimental results have been discussed in the view of solute-solvent interaction.
