Study on Separating Tetrahydrofuran from Mixture of Tetrahydrofuran、Ethyl Acetate and Water

阐述了以水解、液－液萃取、间歇精馏为手段从四氢呋喃、乙酸乙酯、水三元混合物系中分离四氢呋喃的方法．四氢呋喃的纯度超过９８％，收率６１．８％．

It was described that the method of separating tetrahydrofuran from the mixture of tetrahydrofuran、ethyl acetate and water by hydrolysis、liquid-liquid extraction and intermittent rectification. The purity and reclamation of tetrahydrofuran are over 98 % and 61. 8% respectively.
