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.
从含有 1-氯-2,3,3,4,4,5,5-七氟-1-戊烯和一种可能导致可靠性和性能问题的物质的组合物中,生产出该物质含量已降低的 1-氯-2,3,3,4,4,5,5-七氟-1-戊烯。这种生产 1-氯-2,3,3,4,4,5,5-七氟-1-戊烯的方法包括将含有 1-氯-2,3,3,4,4,5,5-七氟-1-戊烯和至少一种从水组成的组中选出的物质的组合物、3,3,4,4,5,5-六氟-1-戊炔、1-氯-3,3,4,4,5,5-六氟-1-戊炔和氧化物组成的组中的至少一种物质与固体吸附剂接触,以从组合物中去除该物质。
