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。
In this paper, the infinite dilution activity coefficient γ_1 (1) ~ of C_ (1-4) alcohol in propylene carbonate (NaI, NaSCN, NaClO_4) 1. There is a good linear relationship between the Inγ_1 ~ of solutes and the mole fraction of salts in the fixative solution, and the salting-out effect occurs. There was a linear relationship between Inγ_1 ~ ∞ and alcohol molecular carbon in alcohol solution at various salt concentrations. The phenomenon of experiment is theoretically analyzed and discussed.
