Carbon Tetrafluoride, Tetrafluoromethane, R14, CF4 Gas
Tetrafluoromethane, also known as carbon tetrafluoride, is the simplest fluorocarbon(CF4) . It has
a very high bond strength due to the nature of the carbon-fluorine bond.
Tetrafluoromethane is the product when any carbon compound, including carbon itself, is burned in an atmosphere of fluorine. With hydrocarbons, hydrogen fluoride is a coproduct. It was first reported in 1926. It can also be prepared by the fluorination of carbon dioxide, carbon monoxide or phosgene with sulfur tetrafluoride. Commercially it is manufactured by the reaction of hydrogen fluoride with dichlorodifluoromethane or chlorotrifluoromethane; it is also produced during the electrolysis of metal fluorides MF, MF2 using a carbon electrode.
