combustion — chemical reaction Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapor, and ash.

The production of tetrafluoroethylene from chlorodifluoromethane is achieved through a high-temperature process, not by a standard laboratory elimination reaction involving acids or bases.

To produce tetrafluoroethylene ( $C_{2} F_{4}$ ), chlorodifluoromethane is heated to temperatures ranging between 600–700 °C (1,100–1,300 °F). While elimination reactions generally involve the removal of atoms or groups from a molecule to create unsaturated compounds—often through the use of reagents or heat—the specific industrial synthesis of tetrafluoroethylene relies on this thermal process to facilitate the necessary molecular transformation.123

Once produced, this gas serves as the primary monomer for the manufacture of polytetrafluoroethylene, a synthetic resin widely recognized for its nonstick properties and chemical resistance.12
