    Abstract: Provided is a method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene where (E)-1-chloro-2,3,3-trifluoro-1-propene and water can be efficiently removed and (Z)-1-chloro-2,3,3-trifluoro-1-propene with higher purity can be obtained at a higher recovery ratio. The method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene includes: distilling a distillation composition which contains (Z)-1-chloro-2,3,3-trifluoro-1-propene, (E)-1-chloro-2,3,3-trifluoro-1-propene and water to remove (E)-1-chloro-2,3,3-trifluoro-1-propene and water as an azeotropic composition or an azeotropic-like composition.

    Abstract: To provide a method for producing 1-chloro-2,3,3-trifluoropropene, whereby it is possible to efficiently remove 1-chloro-3,3-difluoro-1-propyne and/or an oxide from a composition comprising 1-chloro-2,3,3-trifluoropropene. A method for producing 1-chloro-2,3,3-trifluoropropene, in which a composition comprising 1-chloro-2,3,3-trifluoropropene and at least one member selected from 1-chloro-3,3-difluoro-1-propyne and an oxide, is brought into contact with a basic aqueous solution to remove said at least one member selected from 1-chloro-3,3-difluoro-1-propyne and an oxide, from the composition.
