从异丙醇装置副产中分离精制异丙醚的工艺研究

Study on Recovery and Refining Technology of Isopropyl Ether from By-product of Isopropanol

采用萃取精馏和共沸精馏的试验方法,从异丙醇装置副产中分离精制异丙醚可以得到纯度大于99％的异丙醚和纯度大于99.5％的异丙醇,并且产率较高,具有明显的经济效益。

Isopropyl ether separation process from the by-product of isoporpanol and unit operation parameters were researched with method of extractive distillation ind azeotropic distillation. The purity of isopropyl ether was higher than 98% and isopropyl alcohol was higher than 99.5%.
