The following are some synonyms of carbon tetrafluoride:
- carbon tetrafluoride
- carbon(IV) fluoride
- carbon fluoride
The oxidation number of carbon in carbon tetrafluoride is 4.
C + 2F2 → CF4
Carbon tetrafluoride may be made by direct reaction between carbon and fluorine. Charcoals are not suitable as higher weight carbon fluoride form. The reaction can be carried out in a copper tube. Impurities in the gaseous product may be removed by fractional distillation. Carbon tetrafluoride melts at -183.6°C and boils at -127.8°C.
