General information on CF4 / Tetrafluoromethane

Tetrafluoromethane (CF4) (also tetrafluorocarbon) is a chemical compound from the series of fluorocarbons. It is a colorless and odorless gas with a melting point of -184 °C and a boiling point of -128 °C. Tetrafluoromethane is very inert and is not attacked by acids and alkalis. It has a global warming potential of 7349, making it a potent greenhouse gas. Tetrafluoromethane is used as a refrigerant to replace CFCs because it has no depleting effect on the ozone layer. However, because of its high global warming potential, the F-Gas Regulation specifies that equipment using the gases in question should leak as little as possible. Tetrafluoromethane is considered non-toxic. However, it can cause asphyxiation in enclosed spaces by displacing the air. At lower concentrations, a narcotic effect is possible.
