Abstract: The present invention provides a method for separating HFC-245cb and (E)-HFO-1234ze having close boiling points, i.e., boiling points with only 1° C. difference, by extractive distillation from a composition containing the HFC-245cb and the (E)-HFO-1234ze. More specifically, the present invention is a method for separating HFC-245cb and (E)-HFO-1234ze from a composition containing the HFC-245cb and the (E)-HFO-1234ze, the method comprising subjecting the composition to extractive distillation using at least one extractant selected from the group consisting of halogenated hydrocarbons, halogenated unsaturated hydrocarbons, nitriles, ketones, carbonates, alcohols, hydrocarbons, esters and ethers.

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).
