• Canonical SMILES: C(=C(F)F)(F)F
• Inhalation Risk: On loss of containment this substance can cause serious risk of suffocation when in confined areas.
• Effects of Short Term Exposure: Asphyxiation. The liquid may cause frostbite.
• Effects of Long Term Exposure: The substance may have effects on the kidneys, liver and blood. This may result in impaired functions of organs. This substance is probably carcinogenic to humans.
• Description: Tetrafluoroethylene is a synthetic, colorless, flammable gas that is insoluble in water. Tetrafluoroethylene is used primarily in the synthesis of polytetrafluoroethylene resins. It is also used as a monomer in the synthesis of copolymers and as a propellant for food product aerosols. When heated to decomposition, tetrafluoroethylene emits highly toxic fluorocarbon fumes. The primary route of human exposure to this compound is inhalation. Acute inhalation exposure to tetrafluoroethylene may result in irritation of the respiratory tract and buildup of fluid in the lungs (pulmonary edema). Contact with this gas can cause eye irritation. This chemical is reasonably anticipated to be a human carcinogen. (NCI05)
• Uses: In manufacture of polymers and synthesis of fluorinated refrigerants, dielectric media and solvents. In vinyl polymerization, cycloalkylation and addition reactions.
