| titleOfInvention | A kind of tetrahydrofuran-ethyl alcohol-water-toluene mixed solution separation method |
| abstract | The invention discloses a kind of tetrahydrofuran-ethyl alcohol-water-toluene mixed solution separation methods, using it is concatenated and have it is mutually isostructural first extraction azeotropic under lateral line discharging rectifying column and second extraction azeotropic under lateral line discharging rectifying column, structure include top extract azeotropic section and lower part rectifying section；Raw material tetrahydrofuran-ethyl alcohol-water-toluene mixed solution is added in tower from the middle and lower part of the extraction azeotropic section of lateral line discharging rectifying column under the first extraction azeotropic, composite extractant is added in tower by the middle and upper part of extraction azeotropic section, tetrahydrofuran is obtained at the top of extraction azeotropic section, mixed liquor of the rectifying section upper end lateral line discharging containing toluene, bottom composite extractant are recycled to extraction azeotropic section and are recycled；The above-mentioned mixed liquor containing toluene is equally handled in lateral line discharging rectifying column under the second extraction azeotropic.Compared with traditional handicraft, the method for the present invention can effectively improve separating effect, energy consumption needed for simplifying technical process, significantly reducing separation. |
