Beschreibung
Zusammenfassung:	The invention relates to the technical field of fluorochemical industries, in particular to a method for improving out-phase contact efficiency. The method for improving the out-phase contact efficiency is applied to the field of perfluoroalkylpolyether unstable end group fluorination. Out phases include a gas phase and a liquid phase. The method adopts a gas-liquid contact reaction device for countercurrent contact of the gas phase and the liquid phase. The gas-liquid contact reaction device comprises a bubble tower fluorination reactor, a gas ejector is arranged at the bottom of the bubble tower fluorination reactor and connected with a gas storage tank, and the gas ejection speed of the gas ejector is 0.5-10g/min. 本发明涉及氟化工技术领域，具体涉及到一种提高异相接触效率的方法。所述提高异相接触效率的方法应用于全氟聚醚不稳定端基氟化领域；所述异相是气相和液相；该方法包括气相和液相逆流接触的气液接触反应装置；所述气液接触反应装置包括鼓泡塔氟化反应器；所述包括鼓泡塔氟化反应器底部设置有气体喷射器；所述气体喷射器连接有气体储料罐；所述气体喷射器的气体喷射速度为0.5～10g/min。
