Processes for the production of fluoropropanes and halopropenes and azeotropic compositions of 2-chloro-3,3,3-trifluoro-1-propene with HF and of 1,1,1,2,2-pentafluoropropane with HF

摘要

A process is disclosed for making CF₃CF₂CH₃, CF₃CF═CH₂ and/or CF₃CCl═CH₂. The process involves reacting at least one starting material selected from the group consisting of halopropanes of the formula CX₃CHClCH₂X, halopropenes of the formula CClX₂CCl═CH₂ and halopropenes of the formula CX₂═CClCH₂X, wherein each X is independently F or Cl, with HF in a reaction zone to produce a product mixture comprising HF, HCl, CF₃CF₂CH₃, CF₃CF═CH₂ and CF₃CCl═CH₂; and recovering the CF₃CF₂CH₃, CF₃CF═CH₂ and/or CF₃CCl═CH₂ from the product mixture.
