Tetrafluoroethylene

Tetrafluoroethylene (TFE) is a fluorocarbon. It has the chemical formula C2F4. It is a colourless and odourless gas.

It is used to make polymers like Teflon and ETFE. It is suspected to cause cancer.
Production
Production of tetrafluoroethylene starts from chloroform. First, the chloroform is reacted with hydrogen fluoride to make chlorodifluoromethane. Chlorodifluoromethane gives tetrafluoroethylene when heated.
