Abstract
A method for manufacturing hydrofluoroolefin, includes: converting hydrofluorocarbon represented by a formula (1) into hydrofluoroolefin (HFO) represented by formula (2) in the presence of carbon dioxide to obtain a first gas composition containing hydrofluoroolefin and carbon dioxide; and separating carbon dioxide contained in the first gas composition to obtain a second gas composition containing HFO, CRRXCRRX. . . (1), CRR═CRR. . . (2), wherein Rto Rare each independently hydrogen atom or fluorine atom, Ris hydrogen atom, fluorine atom, CH, CHF, CHFor CF, the total number of fluorine atoms of Rto Ris one or more, and the total number of hydrogen atoms of Rto Ris one or more, Xand Xare each hydrogen atom or fluorine atom where Xis the fluorine atom when Xis the hydrogen atom, and Xis the hydrogen atom when Xis the fluorine atom.
