PROBLEM TO BE SOLVED: To provide a method for efficiently decreasing undesired organic substances from (E)-1-chloro-3,3,3-trifluoropropene (OF-1233E) containing the organic substances to obtain highly pure (E)-1-chloro-3,3,3-trifluoropropene.SOLUTION: A method for producing OF-1233E is characterized by bringing a composition comprising OF-1233E and at least one organic substance selected from HCFC-142 isomer, HCFC-244fa, HFC-245fa, OF-1234E, OF-1234Z and OF-1233Z into contact with a solid adsorbent. |
