Abstract
The method according to this disclosure is a method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound formed by replacing at least one of hydrogen atoms included in the unsaturated hydrocarbon with a fluorine atom, from each other and is a method for selectively adsorbing either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound by a porous coordination polymer that includes a metallic ion having a valence of 2 to 4 and an aromatic anion having 1 to 6 aromatic ring(s).
