Perfluorohexane (C 6 F 14), or tetradecafluorohexane, is a fluorocarbon.It is a derivative of hexane in which all the hydrogen atoms are replaced by fluorine atoms. It is used in one formulation of the electronic cooling liquid/insulator Fluorinert for low-temperature applications due to its low boiling point of 56 °C and freezing point of −90 °C.
Data from the 2003-2004 National Health and Nutrition Examination Survey in the United States found the average serum concentration of PFHxS in the general US population to be 1.9 μg/L, with the 10th and 90th percentiles being 0.7 and 8.3 μg/L, respectively. Some studies reported serum PFHxS concentrations in the United States to be gradually ...
As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below). It is an electrically insulating, stable fluorocarbon-based fluid, which is used in various cooling applications. It is mainly used for cooling electronics.
Perfluorohexanoic acid (PFHxA) is a fluorinated carboxylic acid derivative of hexanoic acid.Fluorinated polymers with six carbon or less commonly degrade into perfluorohexanoic acid.
Many perfluorinated compounds have properties that are quite different from their C-H containing analogues. Common functional groups in PFCs are OH, CO 2 H, chlorine, O, and SO 3 H. Electrofluorination is the predominant method for PFC production. Due to their chemical stability, some of these perfluorinated compounds bioaccumulate.
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230, Novec 649, and FK-5-1-12. It is also known as ...
The GWP Chair is Howard Bamsey, who took up the position in January 2019. The Executive Secretary and CEO is Darío Soto-Abril (effective 1 March 2021) and the Chair of the GWP Technical Committee is Dr Jerome Delli Priscoli. Its Patrons are Dr. Ismail Serageldin and Margaret Catley-Carlson.
Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula C n F (2n+1) SO 3 H and thus belong to the family of perfluorinated and polyfluorinated alkyl compounds (PFASs). The simplest example of a perfluorosulfonic acid is the trifluoromethanesulfonic acid .
