<P>PROBLEM TO BE SOLVED: To provide a method for efficiently producing cis-1-chloro-3,3,3-trifluoropropene from 1,1,1,3,3-pentachloropropane and so on. <P>SOLUTION: The method for producing cis-1-chloro-3,3,3-trifluoropropene includes: a step A to obtain a first composition including cis- and trans-1-chloro-3,3,3-trifluoropropene by fluorinating a raw material; a step B to obtain a second composition including hydrogen fluoride and trans-1-chloro-3,3,3-trifluoropropene from the first composition with distillation; a step C to obtain a layer including trans-1-chloro-3,3,3-trifluoropropene as a main component from the second composition with phase separation as a third composition; a step D to obtain a fourth composition including cis-1-chloro-3,3,3-trifluoropropene by bringing the third composition into contact with a catalyst; and a step E to obtain cis-1-chloro-3,3,3-trifluoropropene from the fourth composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
