Patent number: 11046630
Abstract: To produce, from a composition containing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene and a substance that may cause problems in reliability and performance, 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene in which the content of the substance has been reduced. This method for producing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene comprises bringing a composition containing 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene and at least one substance selected from the group consisting of water, 3,3,4,4,5,5-hexafluoro-1-pentyne, 1-chloro-3,3,4,4,5,5-hexafluoro-1-pentyne and an oxide, into contact with a solid adsorbent, to remove the substance from the composition.
