The Uses of Hexadecafluoroheptane
Hexadecafluoroheptane may be employed in solution-phase studies of perfluoropolyalkylene oligomers and in the preparation of fluorinated gel emulsions.
Definition
ChEBI: Perfluoroheptane is a fluorocarbon. It derives from a hydride of a heptane.
General Description
Hexadecafluoroheptane is a common liquid perfluoro-n-alkane. It is reported as fluorinated solvent. Encapsulation of hexadecafluoroheptane (Perfluoroheptane) by a microencapsulation method based on a Pickering emulsion templated interfacial atom transfer radical polymerization (PETI-ATRP) has been reported. Aggregation of diblock semifluorinated in perfluoroheptane (fluorinated solvent) has been reported. Physical properties and commercial/industrial uses of hexadecafluoroheptane has been reported.
Safety Profile
Low toxicity by intraperitoneal route. Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes such as Fí.
Purification Methods
Purify it as for perfluorodimethylhexane. Other procedures include shaking with H2SO4, washing with water, drying with P2O5 for 48hours and fractionally distilling. Alternatively, it has been refluxed for 24hours with saturated acid KMnO4 (to oxidise and remove hydrocarbons), then neutralised, steam distilled, dried with P2O5, and passed slowly through a column of dry silica gel. It has been purified by fractional crystallisation using partial freezing. [Beilstein 1 IV 388.]
