    摘要: Disclosed are processes for a high temperature isomerization reaction converting (E)-1-chloro-3,3,3-trifluoropropene to (Z)-1-chloro-3,3,3-trifluoropropene. In certain aspects of the invention, such a process includes contacting a feed stream with a heated surface, where the feed stream includes (E)-1-chloro-3,3,3-trifluoropropene or mixture of (E)-1-chloro-3,3,3-trifluoropropene with (Z)-1-chloro-3,3,3-trifluoropropene. The resulting product stream includes (Z)-1-chloro-3,3,3-trifluoropropene and (E)-1-chloro-3,3,3-trifluoropropene, where the ratio of (Z) isomer to (E) isomer in the product stream is higher than the ratio feed stream. The (E) and (Z) isomers in the product stream may be separated from one another.

    摘要: A method for producing a desired isomer of 1-chloro-3,3,3-trifluoro-1-propene or a desired isomer of 1,3,3,3-tetrafluoropropene at a high conversion ratio with no use of a solid catalyst is provided. Since no solid catalyst is used, a desired isomer of 1-chloro-3,3,3-trifluoro-1-propene and a desired isomer of 1,3,3,3-tetrafluoropropene can be stably obtained with no undesired possibility that the solid catalyst is deteriorated due to coking or the like caused as a result of long-time use thereof.
