共沸溶液很早就被人们所发现并取得了大量的实验数据，然而，这种现象的理论研究却很少。本文从理论上推导出二元体系共沸液的共沸点与外压、组成和组分沸点的定量关系式，并据此计算了二元体系共沸溶液常压下的共沸点，结果与文献的实验数据有相当好的一致性。本文还对二元体系共沸溶液的存在范围，共沸点相对单组分沸点高低的定性判定作了分析，从而为共沸溶液的研究和应用提供了理论依据。

Azeotropic solution soon discovered by the people and made the experimental data, a lot of however, theoretical study of this phenomenon is rarely. Quantitative relationship between the theoretically deduced two azeotropic distillation liquid boiling point and external pressure, composition and component boiling point, two component azeotropic solution under atmospheric pressure boiling point was calculated accordingly, the result of experimental data and literature are quite agreement. This paper also points the existence range azeotropic solution of the two group, boiling point to determine relative single component boiling point of qualitative analysis is made, which provides a theoretical basis for the research and application of azeotropic solution.
