PROCESS FOR PRODUCING FLUORINE-CONTAINING ALKENE

The present invention provides a process for producing fluorine-containing alkene represented by Formula (2): Rf1C(Rf2)═CH2 wherein Rf1 and Rf2 are the same or different, and are F, H, F(CF2)n- wherein n is an integer of 1 to 5, or H(CF2)m- wherein m is an integer of 1 to 5, with the proviso that Rf1 and Rf2 are not simultaneously H, by heating fluorine-containing alkane represented by Formula (1): Rf1CF(Rf2))CH3 wherein Rf1 and Rf2 are as defined above, in a gas phase to perform a dehydrofluorination reaction, the dehydrofluorination reaction being carried out in the presence of 5 mol or more of anhydrous hydrogen fluoride per mol of the fluorine-containing alkane. The process of the present invention can significantly enhance the selectivity of fluorine-containing alkene without reducing conversion in the production of fluorine-containing alkene from fluorine-containing alkane, such as fluorine-containing propane.
