Method for producing a 1-chloro-2,3,3-trifluoropropene

Provided is a method for producing 1233yd(Z) in which it is possible to efficiently separate 244ca from a composition including 1233yd(Z) and 244ca to obtain high-concentration 1233yd(Z). A method for producing 1233yd(Z) that comprises separating 1233yd(Z) and 244ca by distilling a composition including 1233yd(Z) and 244ca in the presence of an extraction solvent comprising at least one compound selected from the group consisting of alcohols, ethers, nitriles, ketones, carbonates, amines, esters, sulfoxides, hydrocarbons, chlorinated hydrocarbons, and fluorinated hydrocarbons.
