Abstract
The present invention aims to reduce an amount of by-products generated in a reaction step for obtaining fluorine-containing olefin, and thereby to obtain fluorine-containing olefin as a target substance with a higher selectivity than that in the conventional method.In a reaction step for generating fluorine-containing olefin by a dehydrohalogenation reaction from fluorine-containing halogenated propane expressed by a general formula CF3CH(2-n)XnCH(3-m)Xm (wherein n=0, 1 or 2; m=1, 2 or 3; and n+m≦3; and X is selected from F, Cl and Br, independently), fluorochromium oxide having a fluorine content not less than 30% by weight is used as a catalyst.
