Abstract
A method of synthesizing 3,3,3-trifluoropropene including contacting 1,1,1,3-tetrachloropropane, in the vapor phase, at a temperature sufficient to effect dehydrochlorination to form 1,1,3-trichloro-1-propene. The 1,1,3-trichloro-1-propene is isolated and subsequently contacted, in the vapor phase, with hydrogen fluoride in the presence of a fluorination catalyst at a temperature sufficient to effect formation of 3,3,3-trifluoropropene.
