| 摘要 |
The present invention discloses methods to produce cis-1-chloro-3,3,3-trifluoropropene in high yield by the isomerization of trans-1-chloro-3,3,3-trifluoropropene. These isomers are also known as 1233zd(Z) and 1233zd(E), respectively. This is done by using reactive distillation whereby as cis-1-chloro-3,3,3-trifluoropropene is produced, it is removed from the reaction zone. This product removal causes a shift in the thermodynamic equilibrium of the reaction system, forcing the production of additional cis isomer. |
