The reaction can be carried out in a copper tube. Additionally, once CF 4 is emitted into the atmosphere, it takes a very long time to decompose naturally owing to its extremely long atmospheric lifetime of 50000 years [ 8 ]. Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2). Emission of one kilogram of carbon tetrafluoride into the atmosphere has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years. For example, methane has a melting point of -182.5 °C whereas tetrafluoromethane has a melting point of -183.6 °C.
