'''2,2-Dichloro-1,1,1-trifluoroethane''' or '''HCFC-123''' is considered as an alternative to ] in low pressure ] and ] systems, and should not be used in foam blowing processes or solvent applications. It is also the primary component of the ] fire-extinguishing mixture. |
|
|
|
|
|
Its ] is ODP = 0.012, and ] is GWP = 76. HCFC-123 will eventually be phased out under the current schedule of the ]. It was discontinued in new HVAC equipment in 2020 in developed countries but will still be produced for service use of HVAC equipment until 2030. Developing countries can continue to use It in new equipment until 2030 and will be produced for use in service there until 2040. |

HCFC-123 is used in large tonnage centrifugal chiller applications, and is the most efficient refrigerant currently in use in the marketplace for HVAC applications. HCFC-123 is also used as a testing agent for bypass leakage of carbon adsorbers in gas filtration systems, and as the primary chemical in ] fire-extinguishing agent.<ref>{{cite tech report |title=Halotron Emergency Safety Datasheet |number=CAS-306-83-2 |institution=Kidde Fire Systems |year=2002 |url=http://www.associatedfire.com/wp-content/uploads/halotron_msds_sheet.pdf |format=PDF}}</ref> |

==Production== |
|
|
2,2-Dichloro-1,1,1-trifluoroethane can be produced by reacting ] with ] in the gas phase. This is an exothermic reaction and requires a catalyst: |
|
|
:<math>\mathrm{Cl_2C{=}CCl_2 + 3 \ HF \longrightarrow\ Cl_2CH{-}CF_3 \ + 2 \ HCl}</math> |
