Zusammenfassung:There is provided a method of producing HFO with which diluent gas is easily separated even at a low boiling point and which has excellent productivity. A method of producing HFO includes: converting HFC of the formula (1) into the HFO of the formula (2) to obtain a first gas composition containing the HFO and the fluorine-containing solvent, CR1R2X1CR3R4X2 (1), CR1R2═CR3R4 (2), where in the formulae, R1 to R3 are H or F, R4 is H, F, CH3, CH2F, CHF2 or CF3, the total number of fluorine atoms of R1 to R4 is one or more, and the total number of hydrogen atoms of R1 to R4 is one or more. One of X1 and X2 is H, and the other of X1 and X2 is F; and separating the fluorine-containing solvent from the first gas composition to obtain a second gas composition containing the HFO.
