PROCESS FOR PREPARING 2-CHLORO-3,3,3-TRIFLUOROPROPENE

Provided is a process for preparing 2-chloro-3,3,3-trifluoropropene, wherein at least one chlorine-containing compound selected from the group consisting of chloropropane represented by formula (1): CX3CHClCH2Cl, wherein each X is the same or different and each represents Cl or F, chloropropene represented by formula (2): CClY2CCl=CH2, wherein each Y is the same or different and each represents Cl or F, and chloropropene represented by formula (3): CZ2=CClCH2Cl, wherein each Z is the same or different and each represents Cl or F, is used as a starting compound, and said at least one chlorine-containing compound is reacted with hydrogen fluoride while being heated in a gaseous state in the presence of 50 ppm or more of water relative to the chlorine-containing compound. The process of the present invention makes it possible to produce 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) in a manner that is easily conducted, economically advantageous, and suitable for industrial scale production.

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-nCHClCH2—Cl, 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.
