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.
