      Halocarbon production processes are described that can include providing a reactant mixture including a halogenating reagent and a halocarbon reactant. The processes can also include reacting the halogenating reagent and the halocarbon reactant to form a product mixture that can include a halocarbon product and at least a portion of the halogenating reagent, and phase separating the halocarbon product from at least a portion of the halogenating reagent. Systems for separating components of a mixture are described that can include a vessel configured to receive a mixture and maintain a temperature of the mixture within the vessel below about 7° C. The mixture can include a halogen exchange reactant and a halocarbon product. Separation processes are described that can include providing a mixture of a halogen exchange reactant and a halocarbon product. The process can include phase separating the mixture into a reactant phase and a product phase.

    • Claim:
      20. A system for separating components of a mixture comprising a vessel configured to receive a mixture and maintain a temperature of the mixture within the vessel below about 7° C., wherein the mixture comprises a halogen exchange reactant and a halocarbon product.
    • Claim:
      21. The system of claim 20 wherein the vessel is further configured to maintain the temperature of the mixture above about −30° C.
    • Claim:
      22. The system of claim 20 wherein the vessel is coupled to a reactor, the reactor being configured to react the halogen exchange reactant and a halogen in the presence of a liquid phase catalyst.
    • Claim:
      23. The system of claim 22 wherein: the halogen exchange reactant is HF; the halogen is C3Cl6H2; and the halocarbon product is C3F6H2.
    • Claim:
      24. The system of claim 20 wherein the vessel is coupled to a scrubbing apparatus, the scrubbing apparatus configured to receive a halocarbon product mixture from the vessel and expose the product mixture to an aqueous solution.
    • Claim:
      25. The system of claim 24 wherein the aqueous solution comprises one or both of K and Na.
    • Claim:
      26. The system of claim 24 wherein the halocarbon product mixture comprises less than about 2% (wt./wt.) halogen exchange reactant.
    • Claim:
      27. The system of claim 24 wherein: the halogen exchange reactant is HF; and the halocarbon product mixture comprises C3F6H2.
    • Claim:
      28. The system of claim 27 wherein the halocarbon product mixture comprises CF3CH2CF3.
    • Claim:
