Chemie und Industrie
Anwendungen
BeschreibungPerfluorooctane is a fluorocarbon liquid, usually in the form of Perfluorooctane Sulfonate (PFOS). Perfluorooctane is not easily soluble in water, with a solubility of 10 ppm in water, while PFOS is soluble in water, with solubilities reported to be 570 mg/L and 519 mg/L (at 20°C) in pure water and 370 mg/L in fresh water; solubility decreases as the salt content of the water increases. Perfluorooctane and its derivatives are used in retinal detachment surgery and proliferative vitreoretinopathy preparations.
VerwendenPerfluorooctane (CAS# 307-34-6) can be used as a moisture-proof and wear-resistant coating compound. It can also be used to surface coat structure of surgical prosthesis.
