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 ...
Fluorinert is the trademarked brand name for the line of electronics coolant liquids sold commercially by 3M.As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below).
Net global warming potential, GWP, over a 100-year time horizon (normalized to be 1 for R-744, carbon dioxide) Occupational exposure limit/permissible exposure limit in parts per million (volume per volume) over a time-weighted average (TWA) concentration for a normal eight-hour work day and a 40-hour work week
Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (CO 2). [1]: 2232 It is expressed as a multiple of warming caused by the same mass of carbon dioxide (CO 2). Therefore, by definition CO 2 has a GWP of 1.
A water sample is measured as part of a PFAS drinking water treatment experiment, Tuesday, Feb. 14, 2023, at the U.S. Environmental Protection Agency Center For Environmental Solutions and ...
Due to the COVID-19 pandemic, the decision at the conference of parties was deferred to June 2022, where the parties agreed to list PFHxS, its salts and related compounds in Annex a without specific exemptions. [16] Upon entry into force, nations party to the convention are legally bound to take act to cease production and use of PFHxS.
The process proceeds at low voltage (5 – 6 V) so that free fluorine is not liberated. The choice of substrate is restricted as ideally it should be soluble in hydrogen fluoride. Ethers and tertiary amines are typically employed. To make perfluorohexane, trihexylamine is used, for example: N(C 6 H 13) 3 + 45 HF → 3 C 6 F 14 + NF 3 + 42 H 2
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.
