Uses and applications
What the substance is used for, by industry and function
Used in some sterilant mixtures and as a component in some replacements for CFCs as a refrigerant or for halon as a fire suppressant. Replaces CFC-114 in some heat pumps and special air conditioning equipment.
Minimally used as a refrigerant, its primary use as a refrigerant is in blends, mainly R-401A, in industrial process and transport refrigeration equipment. As a stand-alone refrigerant, it has found some niche applications that reach high condensing temperatures as well as an alternative for CFC-114 in some naval chillers.
HCFC-124 is classified as a partially halogenated chorofluorocarbon and was developed as a substitute for fully halogenated chlorofluorocarbons. HCFC-124's main use is in commercial applications as a blowing agent for polystyrene and polyolefin foams in addition to being a component in refrigerant blends.

HCFC-124 is used either in closed systems (for refrigeration uses) or in well-ventilated areas with exhaust systems (in the case of appliance manufacturing).
HCFC-124 is a potential substitute for CFC-11 and CFC-12 use as blowing agent in polyurethane foams. (1-Chloro-1,2,2,2-tetrafluoroethane).
HCFC-124 is a potential substitute for CFCs in aerosols, foams, and refrigerants. (1-Chloro- 1,2,2,2-tetrafluoroethane).
Industrial uses: Intermediate, Refrigerants.
Consumer uses: Refrigerants.
Functional uses
- Refrigerants
How it is made
Common methods of production of HCFC-124 are hydrofluorination of tetrachloroethylene or hydrodechlorination of 1,1-dichloro-1,2,2,2-tetrafluoroethane (CFC-114a). The grade of HCFC-124 purity obtained from either process is greater than 99%.
The most important commercial method for manufacturing CFCs and HCFCs is the successive replacement of chlorine by fluorine using hydrogen fluoride. The traditional, liquid-phase process uses antimony pentafluoride or a mixture of antimony trifluoride and chlorine as catalysts.

Continuous vapor-phase processes that employ gaseous hydrogen fluoride in the presence of heterogenous chromium, iron, or fluorinated alumina catalysts also are widely used. Carbon tetrachloride, chloroform, and hexachloroethane (or tetrachloroethylene plus chlorine) are commonly used starting materials for one- and two-carbon chlorofluorocarbons. The extent of chlorine exchange can be controlled by varying the hydrogen fluoride concentration, the contact time, or the reaction temperature. (CFCs and HCFCs)
