HCFC122

HCFC-122, also known as dichlorotrifluoroethane, is a hydrochlorofluorocarbon. Its chemical formula is C2HCl2F3. It is a colorless liquid at room temperature and pressure. HCFC-122 has been used as a refrigerant and a foam blowing agent, though its use is being phased out due to its ozone-depleting potential and global warming potential.

The production and consumption of HCFCs, including HCFC-122, are regulated under the Montreal Protocol on Substances that Deplete the Ozone Layer. Developed countries have largely phased out the production and consumption of HCFC-122, while developing countries are following a schedule for its eventual phase-out. The phase-out is driven by the understanding that HCFCs contribute to the depletion of the stratospheric ozone layer and also act as greenhouse gases, contributing to climate change.

Alternative substances with lower environmental impact, such as hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs), are increasingly being used to replace HCFC-122 in various applications. The transition away from HCFC-122 is part of a broader global effort to protect the ozone layer and mitigate climate change.
