2,2-Dichloro-1,1,1-trifluoroethane

From WikiMD's Wellness Encyclopedia

2,2-Dichloro-1,1,1-trifluoroethane (also known as HCFC-123) is a hydrochlorofluorocarbon (HCFC) and a type of halocarbon. It is primarily used as a refrigerant and as a replacement for more damaging chlorofluorocarbons (CFCs).

Chemical Properties[edit | edit source]

2,2-Dichloro-1,1,1-trifluoroethane is a colorless, non-flammable liquid at room temperature with a slightly sweet odor. It has a molecular formula of C2HCl2F3 and a molecular weight of 187.38 g/mol. It is soluble in ethanol and ether, but not in water.

Uses[edit | edit source]

The primary use of 2,2-Dichloro-1,1,1-trifluoroethane is as a refrigerant in air conditioning systems and in some types of fire extinguisher systems. It is also used in the electronics industry for cleaning and as a carrier for other chemicals.

Environmental Impact[edit | edit source]

2,2-Dichloro-1,1,1-trifluoroethane is a greenhouse gas and contributes to global warming. However, it is less damaging to the ozone layer than the CFCs it replaced. It has an ozone depletion potential (ODP) of 0.02, compared to 1.0 for CFCs.

Health Effects[edit | edit source]

Exposure to 2,2-Dichloro-1,1,1-trifluoroethane can cause irritation to the eyes, skin, and respiratory tract. It can also cause central nervous system depression and cardiac arrhythmia in high concentrations.

Regulation[edit | edit source]

In many countries, the production and use of 2,2-Dichloro-1,1,1-trifluoroethane is regulated due to its environmental impact. It is included in the list of substances controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer.
