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).

PROCESS FOR PREPARING CHLORINE-CONTAINING FLUOROCARBON COMPOUND

The present invention provides a process for preparing at least one chlorine-containing fluorocarbon compound selected from the group consisting of chlorine-containing fluoropropane compounds represented by Formula (1) : CFnCl3-nCHClCH2Cl, wherein n is 1 or 2, and chlorine-containing fluoropropene compounds represented by Formula (2) : CFnCl3-nCCl=CH2, wherein n is 1 or 2, wherein the process includes the step of contacting at least one chlorine-containing compound selected from the group consisting of 1, 1, 1, 2, 3-pentachloropropane, 1, 1, 2, 3-tetrachloropropene, and 2, 3, 3, 3-tetrachloropropene with hydrogen fluoride in the absence of a catalyst while heating. According to the present invention, the chlorine- containing propane and propene compounds having 1 or 2 fluorine atoms can be prepared by an industrially applicable, simple and effective process.
