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.
本发明提供的一种制备1,2-二氯-3,3,3-三氟丙烯的方法包括在液相中将1,2-二氯-1-卤代-3,3,3-三氟丙烷与碱反应;并在反应继续进行的同时将生成的1,2-二氯-3,3,3-三氟丙烯提取到反应系统外部以回收。根据本发明,通过一种简单的方法可以高产得到1,2-二氯-3,3,3-三氟丙烯。因此,可以在工业规模下生产1,2-二氯-3,3,3-三氟丙烯。
