Title:
METHOD FOR PRODUCING HYDROFLUOROOLEFIN
Document Type and Number:
WIPO Patent Application WO/2017/104828
Kind Code:
A1
Abstract:
Provided is a method for producing a hydrofluoroolefin (HFO) with which a diluent gas is easily separated even at a low boiling point and which has excellent productivity. This method for producing a HFO has a reaction step, in which in the presence of steam, a HFC (1) is brought into contact with a metal catalyst and is converted to a HFO (2), and a first gas composition that includes said HFO and said steam is obtained, and a separation step, in which the steam is separated from the first gas composition to obtain a second gas composition that includes the HFO, wherein HFC/steam is 0.5/99.5 to 80/20. CR1R2X1CR3R4X2 (1) CR1R2=CR3R4 (2) (In formula (1) and formula (2), R1∼R3 are H or F, R4 is H, F, CH3, CH2F, CHF2, or CF3, the total number of fluorine atoms in R1∼R4 is 1 or more, and the total number of hydrogen atoms in R1∼R4 is 1 or more. Of X1 and X2, one is H, and the other is F.)
