Abstract: A new method, i.e.，air flow aided volatilization-condensation process, to separate azeotropic mixtures was proposed. The separation of azeotrope cyclohexane-ethanol was studied to investigate the separation effect of the new method. The experimental results showed that a breakdown of azeotropic composition was achieved for two different feed compositions. Compared with extraction using water as extracting agent, the method of air flow aided volatilization-condensation process has the advantage of not forming a new azeotrope.

摘要： 提出了空气辅助挥发冷凝过程分离共沸物的新方法，以共沸物环己烷-乙醇为研究对象，考察了新分离方法的分离效果。实验结果表明，在两种不同的原料组成下所得产品全部突破了共沸组成。与水萃取法相比，空气辅助挥发冷凝法分离环己烷-乙醇具有不形成新的共沸物的优点。
