A purification method of a fluorine-containing alkylethylene comprises reacting the fluorine-containing alkylethylene with powdered metallic zinc in the presence of an aqueous acetic acid solution. By this method, fluorine-containing alkyl iodide and fluorine-containing alkylethyl iodide, contained as impurities in the fluorine-containing alkylethylene, can be removed effectively, for example, to a level of 1 ppm or below. |
