<p>By extracting hydrogen fluoride from 2,2,3,3-tetrafluorooxetane with a halogenated hydrocarbon, a mixture of 2,2,3,3-tetrafluorooxetane and the halogenated hydrocarbon containing a small amount of hydrogen fluoride is obtained. Said mixture may be distilled at least twice to obtain a mixture of 2,2,3,3-tetrafluorooxetane and the halogenated hydrocarbon containing substantially no hydrogen fluoride.</p> |
