摘要：
Provided is a purification method for efficiently reducing an undesirable organic compound or compound in (E)-1-chloro-3,3,3-trifluoropropene and thereby obtaining (E)-1-chloro-3,3,3-trifluoropropene with high purity. The purification method of OF-1233E according to the present invention is characterized by bringing a composition containing OF-1233E and at least one organic compound selected from the group consisting of HCFC-142 isomers, HCFC-244fa, HFC-245fa, OF-1234E, OF-1234Z and OF-1233Z into contact with a solid adsorbent.
