Abstract
A method of synthesizing 2,3,3,3-tetrafluoropropene (1234yf) from 2-chloro-3,3,3-trifluoropropene (1233xf). The 2-chloro-3,3,3-trifluoropropene (1233xf) is reacted in the vapor phase, in the presence of a catalyst, at a temperature and pressure sufficient to selectively convert the 2-chloro-3,3,3-trifluoropropene (1233xf) to 2,3,3,3-tetrafluoropropene (1234yf) without the use of antimony-based catalysts.
