Physical & Chemical Properties

Physical description & handling notes

• 2-chloro-1,1,1,2-tetrafluoroethane is a colorless nonflammable gas. Nearly odorless.
• Chlorotetrafluoroethane is a colorless odorless gas. It is shipped as a liquefied gas under its own vapor pressure. It can asphyxiate by the displacement of air. Contact with the liquid can cause frostbite. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket.
• Liquid; CBI
• A colorless gas with a faint ethereal odor at room temperature and atmospheric pressure; Colorless liquid under pressurized conditions; [eChemPortal: SIDSUNEP] Colorless volatile liquid; Faint sweetish odor; Gas at ambient temperatures; [MSDSonline]
• Colorless odorless gas; [Hawley] Shipped as liquefied gas under its own vapor pressure; [CAMEO]
• Colorless gas

GHS Hazard Classification

Documented Uses

• Used as a foam blowing agent and refrigerant; [eChemPortal: SIDSUNEP]
• HCFCs: Used as refrigerants, blowing agents, cleaning agents, and fire extinguishing agents (CFC alternatives); [HSDB]
• 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/
