Abstract
The present invention provides a method for producing a target fluorine-containing olefin with high conversion and selectivity using a process comprising a dehydrofluorination reaction of a hydrofluorocarbon. The method comprises a first reaction step comprising subjecting a hydrofluorocarbon to dehydrofluorination in the presence of a catalyst. The hydrofluorocarbon is a compound represented by Formula (1): RfCFYCHZ2, wherein Rf represents a straight or branched C1-3 perfluoroalkyl group, and Y and Z each independently represent H or F wherein when all Zs are H, Y represents F. The catalyst comprises chromium oxide represented by the chemical formula: CrOm (1.5<m<3).
