Abstract
A process for purifying 2,2,3,3-tetrafluorooxetane which contains at least one impurity compound selected from the group consisting of hydrogen fluoride and trifluoropropionylfluoride, which process comprises contacting 2,2,3,3-tetrafluorooxetane with at least one adsorbent selected from the group consisting of silica gel and alumina and causing said impurity to be adsorbed on said particles to remove it from the 2,2,3,3-tetrafluorooxetane.
