Abstract
Provided is a method for storing a fluoro-2-butene by which isomerization reaction is unlikely to proceed during storage. A fluoro-2-butene represented by general formula C4HxFy where x is 0 or more and 7 or less, y is 1 or more and 8 or less, and x+y is 8 contains or does not contain hydrogen fluoride as an impurity. The fluoro-2-butene is stored in a container in which the concentration of hydrogen fluoride is 100 ppm by volume or less in a gas phase portion when the fluoro-2-butene contains hydrogen fluoride.
