摘　　要：本文综述了共沸精馏的特点、分类、共沸剂的选择及相关国内外研究进展。根据所形成的共沸物是否能分离为不互溶的两个液相,共沸精馏可分为均相共沸精馏和非均相共沸精馏。综述了近年国内外共沸精馏技术的应用研究和进展。特别指出在含有少量难分离共沸/近沸杂质的分离方法,具有可行性强,可靠性高等优势,是共沸精馏技术发展的一个重要方向。This paper summarized the characteristics of azeotropic distillation, classification and the selection of entrainer. According to whether the azeotropic mixture is stratified, the special distillation is divided into two type： homogeneous and heterogeneous azeotropie distillation. Recent progress in application and research of the separation technology are introduced. The paper especially indicate that in separation of small amount near boiling/azeotropic impurities, the azeotropic distillation possess some unique advantages, such as high feasibility, strong reliability, etc. The separation of small amount impurities is an important development direction of the azeotropic distillation.
