Abstract
액체혼합물의 비이상성에 관한 구명은 기액평형관계의 이론적 해석에 기초가 된다. 혼합열은 주로 액상의 비이상성에 기인되는 현상으로서 분자크기의 차이, 분자의 분포형태, 분자간의 인력 등에 의하여 지배적인 영향을 받는다. 따라서 혼합열에 관한 연구는 액체용액론에 근거를 두게 된다. 본 고에서는 혼합열에 관한 연구를 group 용액론과 회합용액론을 종합하고 그 이론적 배경을 서술하고자 하였다.
Heats of mixing are the sensitive representation of the nonidealities of the liquid mixtures, which appear to be caused from the differences in molecular size, the type of molecular distribution and the interaction energy of molecules. The vapor-liquid equilibria as well as the heats of mixing for the liquid mixtures have been studied by many authors and the results of those studies were analyzed from the viewpoint of the nonidealities of the liquid mixtures. In this review it is intended to summarize mainly the theoretical background of the heats of mixing based on both the group solution theory and the association theory which were developed in recent years.
