Abstract
A process is disclosed for making CFCFCH, CFCF═CHand/or CFCCl═CH. The process involves reacting at least one starting material selected from the group consisting of halopropanes of the formula CXCHCHX, halopropenes of the formula CXCH═CHand halopropenes of the formula CX═CHCHX, wherein each X is independently F or Cl, with HF and Clin a reaction zone to produce a product mixture comprising HF, HCl, CFCFCH, CFCF═CH, and CFCCl═CH; and recovering the CFCFCH, CFCF═CHand/or CFCCl═CHfrom the product mixture. Also disclosed is a process for making CFCHCHF, CFCH═CHF, and/or CFCH═CHCl. This process involves reacting at least one starting material selected from the group consisting of halopropenes of the formula CXCH═CHand halopropenes of the formula CX═CHCHX, wherein each X is independently F or Cl, with HF and Clin a reaction zone to produce a product mixture comprising HF, HCl, CFCHCHF, CFCH═CHF and CFCH═CHCl; and recovering the CFCHCHF, CFCH═CHF, and/or CFCH═CHCl from the product mixture. The molar ratio of HF to the total amount of starting materials fed to the reaction zone for both of these processes is at least stoichiometric, and the molar ratio of Clto total amount of starting material fed to the reaction zone for both of these processes is 2:1 or less.
