METHOD FOR PRODUCING FLUORINE-CONTAINING OLEFIN

摘要

Disclosed is a method for producing a fluorine-containing olefin, which enables to obtain the object product, namely a fluorine-containing olefin, with a higher selectivity than the conventional methods by reducing the amount of a by-product produced during a reaction process for obtaining the fluorine-containing olefin. Specifically, in a reaction process for producing a fluorine-containing olefin through a dehydrohalogenation reaction of a fluorine-containing propane halide represented by the following general formula: CF3CH(2-n)XnCH(3-m)Xm (wherein n is 0,1 or 2 and m is 1, 2 or 3, while satisfying n + m = 3; and X is independently selected from F, Cl and Br), a chromium oxyfluoride having a fluorine content of not less than 30% by weight is used as a catalyst.
