Abstract
The present invention provides a process for preparing a fluorine-containing propene represented by the chemical formula CF3CFâ•CX1X2, wherein X1 is a hydrogen atom or chlorine atom, and X2 is a fluorine atom, chlorine atom, or hydrogen atom, by reacting a halogenated propene represented by the chemical formula CCIYZCFâ•CX1X2, wherein X1 and X2 are the same as above, and Y and Z may be the same or different and individually indicate a fluorine atom or chlorine atom, with anhydrous hydrogen fluoride in a gas phase in the presence of a chromium oxide or a fluorinated chromium oxide as a fluorination catalyst. The process of the present invention provides a fluorine-containing propene represented by the chemical formula CF3CFâ•CClX, wherein X is Cl, H or F, under relatively mild conditions at a high yield.
