COMPOSITIONS AND METHODS FOR AN INTEGRATED 2,3,3,3-TETRAFLUOROPROPENE MANUFACTURING PROCESS

A method of synthesizing 3,3,3-trifluoropropene including contacting 1,3,3,3-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.

METHOD FOR PRODUCING 2-CHLORO-3,3,3-TRIFLUOROPROPENE

The invention relates to a method for producing 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) from at least one compound A selected from the group consisting of halopropane of formulae CX3CHClCH2X or CX3CFClCH3, or halopropenes of formula CQX2CCNCH2 and CX2═CClCH2X where X independently represents a fluorine or chlorine atom, characterised in that it comprises bringing said at least one compound A into contact with HF in a gaseous phase in the presence of a fluorination catalyst AlF3 or fluorine-bearing alumina in order to form a gaseous flow B comprising 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) et 3,3,3-trifluoropropene (HFO-1243zf).
