Manufacturing method of purified 1-chloro-2,3,3,3-Tetrafluoropropene and purified 1-chloro-2,3,3,3-tetrafluoropropene (Z)

Abstract

There is provided a method of efficiently manufacturing purified 1224yd containing 1224yd at a high concentration from a mixture containing 1224yd and a compound that forms an azeotropic composition or an azeotropic-like composition with 1224yd. A manufacturing method of purified 1224yd, includes making a first mixture of 1224yd and a compound (X1) forming an azeotropic composition or an azeotropic-like composition with 1224yd to be brought into contact with a first extraction solvent to obtain purified 1224yd not substantially containing the compound (X1).
