| 摘要 | A method for producing 1,2-dichloro-3,3,3-trifluoropropene of the present invention includes reacting 1,2-dichloro-1-halogeno-3,3,3-trifluoropropane with a base in a liquid phase; and extracting generated 1,2-dichloro-3,3,3-trifluoropropene to the outside of a reaction system to recover while the reaction is continued. According to the present invention, 1,2-dichloro-3,3,3-trifluoropropene is obtained at a high yield by a simple method. Thus, 1,2-dichloro-3,3,3-trifluoropropene is produced in an industrial scale. | ||
