发明名称 Removal of hydrogen fluoride from 2,2,3,3-tetra-fluorooxetane
摘要 By extracting hydrogen fluoride from 2,2,3,3-tetrafluorooxetane with a halogenated hydrocarbon, a mixture of 2,2,3,2-tetrafluorooxetane and the halogenated hydrocarbon containing a small amount of hydrogen fluoride is obtained. The mixture may be distilled at least twice to obtain a mixture of 2,2,3,2-tetrafluorooxetane and the halogenated hydrocarbon containing substantially no hydrogen fluoride.
