Document Type and Number:
WIPO Patent Application WO/2016/163522
Kind Code:
A1
Abstract:
A process for producing a hydrofluoroolefin (HFO), the process comprising: a step in which a hydrofluorocarbon represented by formula (1) is converted to a hydrofluoroolefin represented by formula (2) in the presence of carbon dioxide to obtain a first gas composition comprising the HFO and the carbon dioxide; and a step in which the carbon dioxide is separated from the first gas composition to obtain a second gas composition comprising the HFO. CR1R2X1CR3R4X2 (1) CR1R2=CR3R4 (2) (In formulae (1) and (2), R1 to R3 are each independently a hydrogen atom or a fluorine atom and R4 is a hydrogen atom, a fluorine atom, CH3, CH2F, CHF2, or CF3, the total number of fluorine atoms in R1 to R4 being 1 or larger and the total number of hydrogen atoms in R1 to R4 being 1 or larger; and X1 and X2 are each a hydrogen atom or a fluorine atom, provided that when X1 is a hydrogen atom, then X2 is a fluorine atom and when X1 is a fluorine atom, then X2 is a hydrogen atom.)
