Document Type and Number:
WIPO Patent Application WO/2010/123154
Kind Code:
A3
Abstract:
The present invention provides an effective, selective, and industrially applicable process for producing 2,3,3,3-tetrafluoropropene. Specifically, the present invention provides a process for producing 2,3,3,3-tetrafluoropropene including reacting 2-chloro-3,3,3-trifluoropropene with hydrogen fluoride in the presence of oxygen and a catalyst comprising chromium oxide represented by the composition formula: CrOm (1.5 < m <3), or fluorinated chromium oxide obtained by fluorinating the chromium oxide.
