Patent ID: 8497401

Claim:
A method for producing 1-chloro-3,3,3-trifluoropropene comprising: a. reacting a starting material comprising at least one hydrochlorocarbon and/or hydrochlorofluorocarbon with a fluorinating agent to produce a reaction product comprising 1-chloro-3,3,3-trifluoropropene, hydrogen fluoride, and 1,1,1,3,3-pentafluoropropane; b. distilling said reaction product to produce a distillate comprising a ternary azeotrope-like composition comprising an effective amount of 1,1,1,3,3-pentafluoropropane, 1-chloro-3,3,3-trifluoropropene, and hydrogen fluoride; and c. contacting said distillate with one or more substances to separate at least a portion of said 1-chloro-3,3,3-trifluoropropene, hydrogen fluoride, and/or 1,1,1,3,3-pentafluoropropane from said distillate, wherein said 1-chloro-3,3,3-trifluoropropene, hydrogen fluoride, and/or 1,1,1,3,3-pentafluoropropane are separated in an amount sufficient to break said ternary azeotrope-like composition.
