共沸精馏技术研究及应用进展

摘要

本文综述了共沸精馏的特点、分类及共沸剂的选择.根据所形成的共沸物能否分离为不互溶的两个液相,共沸精馏分为均相共沸精馏和非均相共沸精馏.介绍了近些年共沸精馏技术的应用研究进展,并提出了非均相共沸精馏技术的优势及展望.%This paper summarized the characteristics of azeotropic distillation, classification and the selection of entrainer. Azeotropic distillation is divided into homogeneous and heterogeneous azeotropic distillation, according to the azeotropic mixture can be separated into two immiscible liquid. Recent progress in application and reserach of azeotropic distillation technology are introduced, the advantages and prospect in technology of heteorgeneous azeotropic distillation are also put forward.
