Process for producing fluorine-containing olefins |
| abstract |
A process for producing a fluorinated olefin by a dehydrofluorination reaction of a hydrofluorocarbon, which comprises obtaining a target product with a high conversion rate and a high selectivity. Is subjected to a first reaction step in which hydrogen fluoride of hydrofluorocarbon is carried out in the presence of a catalyst to produce a fluorine-containing olefin. To the hydro-fluoro-carbon is represented by the general formula (1) R f CFYCHZ 2 (general formula (1) of, R f has 1 to 3 carbon atoms in a straight or a perfluoroalkyl group on the branch, Y and Z are each independently H Or F, wherein when Z is all H, Y is F. The catalyst comprises chromium oxide represented by the formula CrO m (1.5 <m <3). |
