High Quality Content by WIKIPEDIA articles! Pure tetrafluoromethane was first synthesised in 1926. Tetrafluoromethane can be prepared in the laboratory by the reaction of silicon carbide with fluorine. SiC + 2 F2 CF4 + Si 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 fluorine with dichlorodifluoromethane or chlorotrifluoromethane; it is also produced during the electrolysis of metal fluorides MF, MF2 using a carbon electrode. Tetrafluoromethane, like other fluorocarbons, is very stable due to the strength of its carbon-fluorine bonds. The bonds in tetrafluoromethane are with bonding energy of 515 kJ.mol-1. As a result, it is inert to acids and hydroxides. However, it reacts explosively with alkali metals. Thermal decomposition of CF4 produces toxic gases (carbonyl fluoride and carbon monoxide) and in the presence of water will also yield hydrogen fluoride. It is very slightly soluble in water (about 20 mg.l-1), but miscible with ethanol, ether, benzene.
