Hexafluoroethane, with the chemical formula C2F6 and the correct CAS number 76-16-4, is a colorless, odorless gas that finds application in a variety of industrial processes. It is particularly known for its use in semiconductor manufacturing as an etching agent, as well as in the production of aluminum and as a refrigerant.
Characteristics of Hexafluoroethane:
Chemical Formula: C2F6
Molecular Weight: About 138.00 g/mol
Boiling Point: Approximately −87.2 °C
Melting Point: Approximately −192.3 °C
Appearance: Colorless gas
Solubility in Water: Insoluble
Density: Greater than air, approximately 6.17 kg/m³ at 0 °C and 1 atm
Stability: Stable under normal conditions, but may decompose when exposed to high temperatures or strong bases.
Hazards: Non-flammable but potentially asphyxiating in confined spaces due to its high density. Its decomposition products can be hazardous.
Hexafluoroethane is also a potent greenhouse gas with a high global warming potential over a 100-year time horizon.
