Assessment on the toxicity and appliion risk of C4F7N

Apr 15, 2019· C 4 F 7 N (fluorinated nitrile) gas mixture has been utilized as the gas insulating medium to replace the most greenhouse gas SF 6 (sulphur hexafluoride). Nowadays, there are few reports on the toxicity mechanism of C 4 F 7 N and studies on the appliion risk of C 4 F 7 N is insufficient. In this paper, we carried out acute toxicity tests for C 4 F 7 N gas systematically.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule.Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
