C4F10

C4F10, also known as decafluorobutane, is a hydrofluorocarbon with the chemical formula C4F10. It is a colorless, odorless, and non-flammable gas at room temperature and pressure. Decafluorobutane is an isomer of other C4F10 compounds, meaning it has the same chemical formula but a different arrangement of atoms.

This substance finds application as a dielectric gas and a heat transfer fluid. Its excellent electrical insulating properties make it suitable for use in high-voltage equipment such as transformers and switchgear, where it can help prevent electrical arcing. In heat transfer applications, its thermal stability and low toxicity are advantageous.

C4F10 is considered to have a low global warming potential (GWP) compared to many older hydrofluorocarbons, though it is still a greenhouse gas. Its atmospheric lifetime is relatively short. Environmental regulations often govern its use and emissions. Production typically involves fluorination processes of butane or related hydrocarbons.
