摘要： The present invention provides a process for producing a fluorine-containing alkene of the general formula CF3 (CX2)nCF═CH2, wherein X each independently represents F or Cl, and n is an integer of 0 to 2. The process includes a first reaction step of allowing a specific chlorine-containing compound to react with a fluorinating agent under increased pressure in a gas phase in the presence of at least one fluorination catalyst selected from the group consisting of chromium oxide and fluorinated chromium oxide, and a second reaction step of heating the product of the first reaction step in a gas phase under a pressure lower than the pressure in the first reaction step. The process of the present invention can produce a fluorine-containing alkene with a high selectivity with the use of a catalyst that can be easily handled, while suppressing production of by-products that cannot be easily converted into the target or separated.

摘要： 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.
