Abstract: A process for the manufacture of 1-chloro-3,3,3-trifluoropropene (HCFC-1233zd) at commercial scale from the reaction of HCC-240 and HF is disclosed. In one embodiment, HCC-240fa and HF are fed to a reactor operating at high pressure. Several different reactor designs useful in this process include; a stirred-tank reactor (batch and/or continuous flow); a plug flow reactor; a static mixer used as a reactor; at least one of the above reactors operating at high pressure; optionally combined with a distillation column running at a lower pressure; and combinations of the above; and/or with a distillation column. The resulting product stream consisting of 1233zd, HCl, HF, and other byproducts is partially condensed to recover HF by phase separation. The recovered HF phase is recycled to the reactor. The HCl is scrubbed from the vapor stream and recovered as an aqueous solution.

Abstract: Disclosed is a process in which the fluorination of an organic reactant comprising 1,1,1,3,3-pentachloropropane (240fa) with anhydrous HF is conducted in the presence of an effective amount of a phase-transfer catalyst which facilitates the reaction between these incompatible reaction components to produce 1-chloro-3,3,3-trifluoro-propene (1233zd). Other organic reactant materials include 1,1,3,3-tetrachloropropene (HCO-1230za), 1,3,3,3-tetrachloropropene (HCO-1230zd), and various mixtures with or without 240fa.

Abstract: 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.

Abstract: Provided are azeotropic or azeotrope-like mixtures of 1,3,3,3-tetrachloroprop-1-ene (HCO-1230zd) and hydrogen fluoride. Such compositions are useful as a feed stock in the production of HFC245fa and HCFO1233zd.

Abstract: 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.
