chlorodifluoromethane
Quick Summary
Chlorodifluoromethane, also known as Freon 22 or HCFC-22, is a chemical compound composed of hydrogen, fluorine, and chlorine. It is synthesized from chloroform through a reaction with hydrogen fluoride.12
Historically, chlorodifluoromethane was used as a refrigerant, particularly in smaller air conditioning units. It belongs to the broader category of hydrochlorofluorocarbons (HCFCs), which were developed as alternatives to chlorofluorocarbons (CFCs). While HCFCs have a lower ozone depletion potential than CFCs, they still contribute to the depletion of the ozone layer and are potent greenhouse gases. Consequently, their production and use have been increasingly regulated, with a global phase-out scheduled.1234
