An object is to effectively preparing a fluorinated compound by developing a catalyst which is effective in the fluorination of a halogenated alkane or alkene with hydrogen fluoride by a gas phase fluorination or addition of hydrogen fluoride. To this end, a catalyst which comprises a least one element selected from the group consisting of Ti, V, Zr, Mo, Ge, Sn and Pb, and alumina, aluminum fluoride or partially fluorinated alumina is used. This catalyst is prepared by an impregnation method to support the above element on alumina and the like, or a precipitation method in which the catalyst is co-precipitated from a solution containing an aluminum compound and a compound of the above element.
A process for producing a fluorinated saturated hydrocarbon comprising fluorinating a halogenated alkane or alkene having 1 to 5 carbon atoms with hydrogen fluoride in a gas phase reaction or through addition of hydrogen fluoride, respectively, in the presence of a catalyst which comprises:
