空气辅助挥发冷凝过程分离环己烷-乙醇

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。

Study on air flow aided volatilization-condensation process for separation of cyclohexane-ethanol

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.
